Introduction In software development, especially when dealing with APIs, it’s crucial to have data accurately represented according to the expected formats. In this case, you're working with gRPC and need to customize how bytes fields are marshaled to JSON. If your application exchanges data including SHA-1, SHA-256, and UUIDs as bytes, you might find the default behavior of converting bytes to base64 rather limiting. Let’s explore how to implement a custom marshaler in Go to handle this effectively, ensuring that your specific use case can accommodate hexadecimal encoding instead of base64. Why This Issue Occurs The default behavior for handling bytes in gRPC-Gateway is to convert them into base64 later when transforming them into JSON. This decision can be frustrating when hexadecimal re…  ( 5 min )

One major feature of Javascript is it is a single-threaded environment; it can only execute one task at a time. When one function calls another, the JavaScript engine carefully tracks these calls using a mechanism known as the "call stack."; A data structure that follows the LIFO (Last In, First Out) principle, a function call is added (pushed) to the top of this stack. When the function, and removed (popped) from the stack when the function completes its execution. Imagine the call stack as a tower of tasks, where each new function call adds another level to the tower. function greet() { console.log("Hello!"); sayName(); console.log("Goodbye!"); } function sayName() { console.log("Ny name is David."); } greet(); When this code runs, the engine first places greet() on the call s…  ( 7 min )

Designing composable, maintainable, and developer-oriented interfaces for LLM apps Large language models (LLMs) introduce a fundamentally different interaction model. Instead of submitting static form data to deterministic APIs, users compose flexible, evolving instructions( prompts)to drive behavior. The UI is no longer just a form. It becomes a live environment for crafting, executing, and refining these prompts. This shift introduces new engineering challenges: Unstructured, contextual input: prompts resemble natural language, code, or hybrids Probabilistic, variable outputs: repeated prompts yield different results Exploratory iteration patterns: success depends on trying, comparing, adjusting To support this, frontend engineers must rethink how they model state, compose components, an…  ( 6 min )

Creating a dynamic and consistent chart area is essential when developing a website that showcases data by region. If you're facing an issue where the chart's appearance varies based on the magnitude of the data, you're not alone. Understanding the Problem When you use libraries like Chart.js to visualize data, the space allocated for the y-axis can change depending on the scale of your data values. For instance, larger numbers may create more left-side margin space, inadvertently altering the chart's shape and making comparisons less intuitive. This is especially evident in your provided images where different datasets create discrepancies in chart sizing. Why Does This Happen? The variation in chart size occurs because the default behavior of bar charts in Chart.js automatically adjusts …  ( 4 min )

Amazon ECS (Elastic Container Service) has just rolled out support for Amazon EBS Provisioned Rate for Volume Initialization — a powerful feature that speeds up EBS volume readiness when attaching from snapshots. This update is a game-changer for ECS workloads like: 🧪 ETL pipelines 🎞️ Media transcoding 🤖 Machine Learning inference With this enhancement, ECS tasks and services on both Fargate and EC2 launch types can now attach fully-performant EBS volumes right from the get-go! Previously, you could initialize ECS task volumes from EBS snapshots using snapshot-id, but performance was not guaranteed right away — data restoration from the snapshot could slow things down. Now, with Provisioned Rate for Volume Initialization, you can: ✅ Specify the initialization rate when creating volumes from snapshots In real-world production scenarios, time is money: ⏱️ ETL jobs don’t wait — they need volumes ready instantly 📺 Media processing workloads are time-sensitive 📦 ML inference needs low-latency, high-throughput disk access By provisioning initialization rates, you reduce startup delays and ensure consistent performance across containers. Define EBS volume attributes (size, type, IOPS, throughput). Attach volume to ECS task using a snapshot (snapshot-id). Specify the initialization rate during provisioning. ECS ensures attached volumes are fully-performant on task launch. ✅ Amazon ECS on Fargate ✅ Amazon ECS on EC2 ✅ ECS Tasks and Services You can also set this rate in ECS Task Definitions or Service Configurations, making it easy to standardize performance across deployments. This update from AWS bridges the gap between fast EBS volume access and containerized workloads. If you’re building data-intensive, high-performance applications on ECS, it’s time to take advantage of predictable storage performance with Provisioned Rate Volume Initialization.  ( 4 min )

Imagine standing at the threshold of a technological revolution so vast, it could redefine an entire continent's place in global innovation. This is precisely the position Europe finds itself in today. With a massive investment of €200 billion—the centrepiece being five AI Gigafactories—the EU intends not only to catch up but to leap ahead in the global race for artificial intelligence.

Ever try to monitor a laser system in real-time... with Excel? Yeah, I’ve been there. A couple years ago, I was asked to build a dashboard for a medspa’s laser lipo machine. They wanted live data. Not just logging—but pulse-by-pulse, second-by-second monitoring. My first thought? “This is gonna be a nightmare.” You’d think there’d be some ready-made solution, especially in places as tech-savvy as a Medspa in Chicago. But nope. At first, we tried to jury-rig a CSV parser that pulled in log files every 10 minutes. Huge mistake. We missed surges in energy output, and one day the machine overheated mid-session. That’s when it hit me: we needed true real-time telemetry. Enter: Node.js (or Python, if that’s your jam). Here’s the quick-and-dirty framework I came up with: Stream the machine’s da…  ( 4 min )

When performing arithmetic with unsigned types in C++, especially with types like std::uint8_t, it's common to encounter questions surrounding modular arithmetic behavior. Specifically, many developers wonder if they can detect when a subtraction operation underflows (i.e., wraps around) without explicitly comparing the two operands. Understanding Subtraction with Unsigned Types In C++, when subtracting one unsigned integer from another, the result is constrained within the limits of the type. For std::uint8_t, this means that values wrap around when the result would go below zero. For example, subtracting 5 from 3 results in 254 due to the wrapping behavior inherent in unsigned types. To validate whether an underflow occurred during subtraction, comparisons are typically used. However, th…  ( 5 min )

Muito já se discutiu sobre as funcionalidades da IA Generativa: modelos de linguagem, engenharia de prompts, automação de conteúdo. Mas o verdadeiro ponto de inflexão não está na tecnologia em si — e sim na sua capacidade de subverter modelos de operação que antes pareciam inquestionáveis. Não se trata mais de "adotar IA" como ferramenta, mas de compreender a IA como um agente de transformação organizacional. Alguns sinais são evidentes: Propostas comerciais que levavam horas para serem montadas agora podem ser redigidas em minutos, com base em dados contextuais e históricos de negociação. Campanhas de marketing não precisam mais ser montadas do zero: são concebidas, testadas e ajustadas por sistemas autônomos com base em comportamento e intenção. A IA Generativa não está apenas automatizando processos. E, talvez mais importante: está alterando o que esperamos das organizações e dos profissionais que nelas atuam. O risco real não é ser substituído pela IA. Não é mais suficiente usar IA. A pergunta, então, não é mais “como aplicar essa tecnologia?”. Sua organização está preparada para repensar seus fundamentos operacionais à luz da Inteligência Artificial Generativa — ou será refém de sua própria inércia? 📌 O debate precisa sair do nível técnico e alcançar o nível estratégico.

But here’s the kicker — most businesses compare providers solely based on cost or brand name. And that’s where they go wrong. AWS has the widest range of services, but are you using them efficiently? Azure integrates deeply with Microsoft products, but is that always an advantage? Google Cloud boasts AI and data capabilities, but what if your use case doesn’t need it? If you’ve ever asked: “Which cloud is the best?” “What’s the real difference between AWS, Azure, and GCP?” “Which provider is right for my workload?” … you’re not alone. We’ve seen startups and even large enterprises spend weeks debating, only to realize they missed core decision criteria. Here’s what often gets overlooked: Compliance & Governance: Which cloud helps you stay audit-ready with less manual overhead? Hidden Cost Models: Are you aware of ingress/egress charges and region-based billing quirks? Developer Experience: How fast can your team get up and running with a new toolset? Multi-Cloud or Vendor Lock-in? Should you optimize for performance, flexibility, or both? These questions aren’t just technical. They’re deeply tied to your business strategy and long-term scalability. We’ve Broken It All Down for You Whether you’re: Migrating your first app Scaling a SaaS product Building a data pipeline Or just tired of jumping between dashboards… This guide will help you make a confident, informed decision, not just one based on marketing slides. Read now Comparing Cloud Providers: AWS vs Azure vs Google Cloud Bonus: We’ve also included a quick cloud decision checklist to help your team reduce the confusion. If you’re serious about building in the cloud don’t choose blindly. Choose smart.  ( 4 min )

Alright folks, let's talk persistence. If you've been following along with the Vercel AI SDK v5 canary journey, you know we've covered a lot about the new message structures (UIMessage, UIMessagePart), how the client-side state is managed with useChat (especially with that id prop behaving like a mini ChatStore), and how the server-side flow including onFinish and tool calls works. Now, how do we actually save all this rich conversational data so users can come back to their chats? This isn't just about stashing some text in a database anymore. With V5, we're dealing with structured, multi-part messages that are key to those "generative UI" experiences. Getting persistence right means your users get a pixel-perfect restore of their chat, tools and all, and you, the developer, get a system …  ( 37 min )

As a quick reminder, we're building on concepts from previous posts: UIMessage and UIMessagePart (the new message anatomy), v5's streaming capabilities, V2 Model Interfaces (especially LanguageModelV2FunctionTool), and the overall client/server architecture. If those are new to you, you might want to glance back. 🖖🏿 A Note on Process & Curation: While I…  ( 34 min )

CSS can feel simple—until it's not. In interviews for frontend roles, seasoned developers often face CSS questions that test deeper understanding of the cascade, specificity, layout behaviors, and browser quirks. In this post, I’ve compiled 10 advanced and tricky CSS questions you're likely to encounter, along with detailed answers and examples. margin: auto center a div vertically? Question: .center { margin: auto; height: 100px; } Why doesn't this vertically center it inside its parent? Answer: margin: auto works for vertical centering only if: The parent has a defined height The child is not using position: static or position: relative The child has a fixed height But most importantly, vertical margin: auto doesn’t work in normal flow—you need flex or grid for that.

When working with SQL, one of the common inquiries developers face is whether the CASE statement in their SELECT clause effectively filters records or if they also need to replicate the same conditions in the WHERE clause. This question is particularly pertinent when grouping certain entries, such as teams, and seeking clarity on how SQL evaluates these expressions. Understanding SQL CASE and WHERE Clauses The CASE statement is primarily used to create conditional logic inside your SQL queries, particularly in the SELECT clause. Its purpose is to return specific values based on the conditions you define. However, the WHERE clause serves a different function; it limits the rows returned by the query based on certain conditions. Why You Might Need Both CASE and WHERE In your specific example…  ( 4 min )

Read the full article here Why Cybersecurity Metrics Matter in 2025 Modern cyber threats demand much more than reactive defense. Effective cybersecurity management starts with tracking the right metrics — providing clear insights into your organization’s risk posture and the real-world effectiveness of your cyber defense strategy. Recent industry studies highlight a significant gap: PWC found only 22% of CEOs are confident in their risk exposure data, while just 15% of organizations are satisfied with their information security reporting (EY Global Information Security Survey). This makes reliable security performance tracking and data-driven risk management in cybersecurity critical for 2025 and beyond.

In this article, we'll explore how to effectively apply CSS styles in your React project. React components rely heavily on proper styling, and sometimes integrating CSS can be tricky, especially when you encounter common pitfalls. One such issue could occur when handling escapes like '>' in your JSX code. Understanding CSS in React React allows you to use styles in multiple ways, including inline styles, traditional CSS stylesheets, CSS Modules, and styled-components. Each approach offers unique advantages. Why Use CSS in React? Using CSS correctly in React helps maintain a clean design and enhances user experience. It allows you to style components dynamically and reuse styles across your application, making it easier to manage. Common CSS Injection Issues One problem that you may encount…  ( 4 min )

What is @Scope This is a class-level annotation that allows the developer to define the scope of a Spring bean. By default, all Spring beans are singletons, but by using this annotation, you can modify that to the following scopes: singleton: the default one, where Spring will create a single instance and share it throughout the application wherever the bean is needed. Prototype: This scope creates a new instance whenever the bean is requested. Request: Spring will create an instance of the bean that will live until the HTTP request is done. session: Spring will create a bean specific for that session; for each session, it will be a new bean. Resource management: This annotation will give you the flexibility you need to manage the resources of your application and help you have more cont…  ( 7 min )

AI is changing very fast and Large Language Models (LLMs) have made things a lot easier. Yet, they face a fundamental limitation: they forget everything between sessions. What if there could be a way to have a personal, portable LLM “memory layer” that lives locally on your system, with complete control over your data? Today, we will learn about OpenMemory MCP, a private, local-first memory layer built with Mem0 (memory layer for AI Agents).

Oracle Corp. has released some time ago an installation kit of Oracle 19c (version 19.19) that supports ARM-based devices. This package can be successfully used to install the database on a Raspberry Pi 5. Currently, Oracle Linux (both version 8 and 9) is not installable on the Raspberry Pi 5. However, future releases of Oracle Linux are expected to address this limitation. I tried on RPI4 couple of years ago and failed to find a solution then after some long investigations I gave up once I found that it is a problem of CPU — not yet prepared for Oracle Db code. The idea of running a functional database on the Raspberry Pi has always stayed with me. Therefore, after reading on several blogs that the Raspberry Pi 5 features an improved processor, I decided it was worth attempting the setup …  ( 14 min )

Introduction Docker registries are essential nowadays in a world of containerized workloads. Want to run your app on Kubernetes? You need to push it to a registry first. If you don't want to pay for a managed, private registry service, you self-host your own. The biggest pain point of Docker registries is storage. If you choose to store registry data on a local disk, you are limited by capacity. Over time, registries accumulate a lot of garbage in the form of blobs referenced by old images that are not needed anymore. Many registry implementations, such as CNCF Distribution, offer garbage-collection mechanisms to delete unreferenced blobs and free up storage space. However, for that to happen, old images (tags) referencing them have to be deleted first. There are implementations like Har…  ( 4 min )

Read this article on Signadot. Testing in-progress changes together, across services, without merging early or coordinating a full rollout, shouldn’t be so painful. “Hey, don’t merge that yet, I still need to test with my service.” Sound familiar? Coordinating changes across microservices during feature development always starts simple. When your whole stack fits in a single repo or an EC2 box, it’s not a big deal. But fast-forward a bit, and you’re juggling 20, 40, maybe hundreds of services owned by different teams, moving on different timelines, and depending on each other in subtle, undocumented ways. Suddenly, a small change to an internal API breaks someone else’s staging. A frontend pull request (PR) is stuck waiting on a backend deploy.

As a developer, my core expertise lies in frontend and mobile app development using React Native. Given that both frontend and React Native leverage JavaScript, I've explored cross-platform solutions like react-native-web. However, this approach often means sacrificing certain advantages inherent to each platform, such as straightforward CSS styling or enhanced SEO capabilities. In my frontend work, I also utilize a range of technologies tailored to specific client needs, including Astro.js, React, Next.js, or even vanilla HTML, CSS, and JavaScript. This often leads me to the fundamental question: how can we write code once and deploy it across web, Android, and iOS while maintaining excellent design, SEO, and performance?

When I started learning FE, I began with React - like many others. It's the most popular library, and if you search for job opportunities there are abundant. And at that stage, you should have only one goal/priority, getting hired and gaining experience. So it's only reasonable to start with React. I learned React through class component, and yes, they are deprecated. But understanding gave me deeper grasp of how React works under the hood (lifecycle methods, binding, rendering). Eventually, I landed my first job working on Vue project. It wasn't a conscious shift, but it was a opportunity. Over time I came to appreciate Vue, and while writing this, I feel like a need to promote it. Especially through lens of someone who also mentored new developers in React, on bootcamp.

E talvez você se identifique... Desde 2023 venho trabalhando como dev profissionalmente. Sempre fui o tipo de dev "raiz", que gostava de codar, passar horas (ou noites inteiras) imerso em projetos que nem eram meus. Saí de outro estado pra Natal-RN com a cara e a coragem. Aluguei um canto só com a roupa do corpo e fui construindo meu espaço — e finalmente, trabalhando como dev. Amava o que fazia. Mas com o tempo, o cenário mudou. A inflação subindo, custo de vida aumentando, e meu salário... estagnado. A vontade de procurar empregos melhores chegou, deu certo, o salário subiu... etc. Mas há alguns meses, no fim de 2024, percebi que tinha perdido o amor pela programação. O código virou só uma moeda de troca. Eu só queria o dinheiro. E aí veio o maior problema: ❌ Não me atualizei ❌ Fiquei pra trás ❌ Acabei o último contrato PJ e tive uma dificuldade ENORME pra me realocar Enquanto devs realmente bons escolhem onde querem trabalhar, eu tava no limbo, tendo que dar vários passos pra trás. A pergunta martelava: “O que tem de errado comigo?” Depois de muito pensar (e muita autoanálise), percebi: Eu tinha perdido meu lado dev raiz. Aquele que curte aprender, codar por prazer, mergulhar nos porquês das coisas. Tava tudo no automático. Então, comecei do zero de novo. Voltei pro básico: codando, lendo, contribuindo, errando, aprendendo. Dessa vez com prazer. E percebi que tinha me desviado do meu caminho. Antes de olhar pra vaga, eu perguntava: “Quanto paga?” Se não fosse "bom o bastante", eu nem tentava. Agora, a primeira pergunta é outra: “O que posso aprender aqui?” Voltei a contribuir, voltei a movimentar meu GitHub, voltei a fazer parte da bolha dev disso que eu gosto, que eu sempre sonhei, e de onde eu simplesmente me perdi. E aí? Você ainda é dev, DEV? Ou tá só no piloto automático?  ( 3 min )

When set to imagine practical, easy-to-use, lightweight applications of Divooka, a visual novel game framework is one of those that came to mind. Visual novels should be such a straightforward type of application to build, yet surprisingly, it's not generally easy to find ready-to-use tools available for them. Of course, one can use Defold, Godot, Unity 3D, or even Unreal to build such a game — or the more technically inclined might just use SFML or other lower-level graphics libraries. Still, it's a lot of work to get a conceptually straightforward task done. Much like building an LLM agent or chaining different AI services together — it's straightforward, it's visual, it describes some kind of workflow or dataflow — then it's a good fit for Divooka.

If you're transitioning from JavaScript to TypeScript, you may encounter type-related issues that can be frustrating. In this article, we'll delve into how to properly push an object into a MongoDB array using TypeScript and address common errors you may face in the process. Understanding the Error Your current error occurs because TypeScript is more strict with types compared to JavaScript. The error message you’re experiencing: Type '{ answers: {}; }' is not assignable to type 'PushOperator'. This suggests that TypeScript expects a specific type for the answers field, but you are passing an empty object {}, which doesn't match the expected type. Setting Up Type Definitions To resolve this, you need to define the type of the answers array properly. Assuming that answerObj represents the …  ( 4 min )

It has always been an industry of constant evolution, but the rise of artificial intelligence has multiplied the productivity of those who adopted it early. This new reality, with teams capable of building faster than ever, shines a light on something many leaders still don't want to see: the main bottlenecks are often not in development, but in how we manage processes and make decisions. When developers become more efficient, tasks are delivered faster, and AI tools can automate or accelerate repetitive work, the real obstacles are exposed: unnecessary processes, unproductive meetings, outdated hierarchies, and a constant need to “feel in control.” All of this slows teams down.

Solana has made a name for itself in the blockchain space as one of the fastest and most scalable platforms in the industry. But what’s the secret behind its speed? It all starts with time. More specifically — Proof of History (PoH). In this blog post, we’ll break down what PoH is, how it works, and how it helps Solana achieve high throughput, low latency, and fast finality — all in a way both beginners and developers can understand. In most blockchains (like Bitcoin or Ethereum), time is a vague concept. Each block is timestamped by validators or miners — but there’s no standardized clock. This creates a challenge when trying to organize transactions quickly and securely. Nodes must constantly communicate to agree on order, which slows everything down. 🧠 Enter Proof of History: Time Befo…  ( 4 min )

If they said no that means they probably spent a good amount of time trying to replicate the issue but were not able to, now it is on you to guess what what the problem is. Good luck. If you were the one that worked on the feature that is defective you may have some intuition guideline, "this is probably because I did not test this properly when I coded it", in this case you may already know the so…  ( 4 min )

Introduction Experiencing a segmentation fault in your Perl script can be quite frustrating, especially when everything seems to execute correctly. If you're encountering a segmentation fault immediately after calling exit 0;, yet your script completes its logic successfully, it indicates an underlying issue that needs to be addressed. This article aims to help you diagnose and resolve segmentation faults in your Perl scripts, focusing on factors such as global destruction and diagnosing techniques. Why Does This Happen? Segmentation faults usually occur due to memory management issues, such as dereferencing invalid pointers or memory corruption, which aligns with the error message you received: mremap_chunk(): invalid pointer. In the case of Perl, this can happen if your script has global…  ( 5 min )

My AI-Driven Coding Workflow: Fast, Dirty, Smart For years, I’ve followed a simple, effective development rhythm: Refactor the existing code to make space for what’s coming. Spam code the new part—quick and dirty—just get it working. Refactor again, clean it up, make it readable and reusable. Commit. It’s always worked. It still does. But now there’s AI. The last few years have made AI coding assistants usable, stable, and practical. So I’ve adapted my process. Here's how it looks today: Start with a clean working tree. No changes, no mess. This has always been good practice, but it’s critical now. Why? Because AI can (and will) generate garbage. If it does, you need to scrap everything fast. You can’t "undo" AI-generated logic. You just reset. Whether by hand or with AI help, p…  ( 4 min )

There are plenty of articles about remote work setups, digital tools, and productivity hacks. But every now and then, someone shares something that shifts your entire perspective. Recently, I came across a unique article featuring Ashkan Rajaee, an entrepreneur who set up a mobile workspace in the middle of the California desert. It was more than a productivity post. It was a blueprint for focus, structure, and intentional work. 👉 Read the full article on LinkedIn Ashkan didn’t just show off his gear or daily habits. He demonstrated how a simple, controlled environment can power serious work. The desert setup is stripped of noise, clutter, and distraction. What’s left is clarity. The tools were simple.

Why created this chatbot? 🤔 In today's fast-paced work environment, HR teams are constantly challenged to provide timely support, answer repetitive queries, and ensure employees have easy access to policies and resources. While traditional chatbots offer basic Q&A, the true power of AI lies in its ability to understand context, invoke external tools, and deliver personalized assistance. This HR Assistant Chatbot was created to showcase how the OpenAI API can go beyond simple chat completions—leveraging function calling to process leave requests, fetch payslips, and direct general queries to a rich knowledge base of company HR policies. The result is a dynamic, interactive assistant that not only answers questions but also performs actions, making HR support more efficient and engaging f…  ( 4 min )

A good programming language should model it's domain in the most straight-forward way - that way there are no rough edges, no friction. The programmer has no gotchas to work around, the code flows naturally. Distributed programming in modern mainstream languages is not that experience, and in this blog we will go over a part of the solution, the one having to do with coordination of distributed actors. OOP models a program as an interaction between objects, and its implementation in most modern languages work well in a single-threaded context. But as soon as concurrency gets introduced - you either introduce a whole different mechanism than the objects you've been building with up til this point (threads and mutexes and thread-local variables), or an event loop, and a split in the laguage …  ( 7 min )

When you need to deploy a simple HTML page (like one generated by AI), or quickly share some design drafts, or deploy a small website from a ZIP package, what tools do you usually use? A lot of the time, you either find hosting too expensive or the setup process too complicated. Recently, I discovered an online tool called Pages Drop, and it seems pretty neat. It's essentially a place for hosting and sharing files, and crucially, it's completely free and very convenient to use. Why do I think it's worth sharing? Mainly for these reasons: Although there are similar products, such as Tiinyhost, Static App, etc., the free plans have very few resources and are very restrictive. The free tier is quite generous: Completely Free: The core features are genuinely free to use. Unlimited File Upl…  ( 4 min )

Hello Dev.to readers! This time, we decided to adopt a slightly more serious tone and tackle a serious topic. In our New Gen Atari project, we hit rate limits hard. After that mess, we finally turned to the documentation. To keep you from falling into the same trap, I wanted to write a piece with above-average seriousness. API rate limits cap the number of requests you can make to an API in a given timeframe (e.g., 100 requests per minute). Exceeding these limits results in rejected requests, disrupting your application. They’re standard across platforms, whether free or paid tiers. Limits serve three key purposes: Security: Protect servers from malicious request floods. Resource Management: Ensure fair access for all users. Cost Control: Prevent excessive server resource consumption. Igno…  ( 5 min )

I recently set up Home Assistant and started exploring the world of smart home automation. One of my first—and now favorite—automations is part of my morning routine. Let’s be honest: waking up early sucks. Alarm clocks are loud, annoying, and stressful. I wanted something more peaceful to get me out of bed. And I found it… I wake up through the smell of coffee and the gentle bubbling sound of a moka pot. 😌 I bought this moka machine from Bialetti: https://www.bialetti.com/ee_en/moka-elettrika.html It’s called the Moka Elettrika, and it runs on electricity. I connected it to a smart plug that’s controlled by Home Assistant. At 7:55 AM, the smart plug turns on, powering the moka pot. The moka starts brewing right away. At 8:10 AM, the plug turns off again. By the time I'm awake, the apartment smells like fresh coffee, and I hear that cozy, comforting moka pot bubbling away. It’s such a calm and natural way to wake up—no loud noises, no stress. This tiny automation has made a huge difference in how I start my day. If you're into smart home stuff (or just love coffee), give it a try!  ( 3 min )

There’s a strange paradox in tech: someone can be a solid developer, lead projects, write clean code, and still fail interview after interview. Not once, but over and over again. And we’re not talking about juniors. I’ve seen senior engineers freeze mid-sentence, forget terminology, or just walk away feeling like they bombed, even though they knew the answers. If that sounds familiar, you’re not alone. I’ve worked with developers for years: hiring them, preparing them, evaluating them. And here’s the truth: if you’re struggling with interviews, it doesn’t mean you're unqualified. It means the format is broken. In theory, a technical interview checks if you know your stuff. In reality, it’s a pressure cooker. Here’s what it throws at you: limited time unfamiliar phrasing of questions z…  ( 4 min )

Google just paid $1.375 billion to Texas for secretly tracking users, collecting geolocation, voiceprints, and facial recognition data even with privacy settings disabled. The headlines scream “Big Tech scandal” — but here’s the real message: If your app handles user data, you’re part of this conversation. And if you’re using tools like Firebase, Google Analytics, or Meta Pixel in production without understanding what’s being captured, you’re one misconfigured SDK away from a privacy disaster. 🔍 So, What Should Developers Do? Re-check what your analytics are logging. Google Analytics 4 tracks more than you think by default, especially if you’ve enabled Enhanced Measurement. Alternative: Try Plausible or PostHog. They’re privacy-first, self-hostable, and GDPR-compliant. Audit your use of location data. If you’re using React Native Geolocation, are you requesting location only when needed? In web apps, check the navigator. Geolocation calls, are you storing or sharing that info? Facial recognition libraries? Tread carefully. Read your dependencies’ privacy policies. Cookies and localStorage: keep them clean. Use libraries like cookie-consent and tools like Cookiemonster.dev to flag risky behavior early. 🧠 The Bottom Line As devs, we build the foundation of user experiences, and that includes privacy-first defaults. Not because it’s trendy, but because it’s now a requirement.  ( 3 min )

When you create a new project in Android Studio, especially after an upgrade like the Bumble Bee version, you may face issues where coding errors are not detected. This can be frustrating as you're working with your Dart code. In this article, we'll explore potential reasons behind this problem and how to fix it effectively. Why Are Errors Not Showing Up in Android Studio? Dart is a language that uses a strong type system, which means it usually identifies errors during development. If errors are not appearing, there are a few possible causes: IDE Configurations: Sometimes, after an update, settings may return to defaults or change unexpectedly. Project Settings: Your project configuration might not be set up correctly for error detection. Dart and Flutter SDK: Issues with the SDK installa…  ( 5 min )

When we talk about giving feedback, most of the advice out there focuses on how to say the thing. But what I have learned over time is that the real magic happens before the conversation even starts. Setting the stage can be the difference between feedback landing as a gift or feeling like an attack. Some of the most effective feedback conversations I have had - both from giving and receiving - actually started with a letter. When there's a lot to say, taking the time to write it down helps in more ways than one. It lets you rewrite, refine, and make sure the message you intend is the message that gets carried forward. You can catch moments where your tone might be too harsh, or where you're speaking from frustration instead of clarity. From the recipient's perspective, it's a game-change…  ( 4 min )

Welcome to the next pikoTutorial ! Imagine you're building an application that processes some data and once it's done, the user needs to be notified about the result. Since you don’t want to hard-code the notification logic, it’s better to allow the user to register a custom function that will be called automatically after the data processing completes. std::function for callback registration One of the most flexible ways to implement callbacks in C++ is by using std::function. std::function can store and invoke any callable object (functions, lambdas, or function objects) that matches a specific signature. The overall syntax is: std::function name; Let’s define a ProcessData unction that accepts a callback and notifies the user once processing is complete. #include #include // Type alias for the callback type using CallbackType = std::function; // Function accepting callback as an argument void ProcessData(const CallbackType& callback) { // Simulate data processing std::cout << "Processing data" << std::endl; // Notify user via callback callback(true); } // Callback function definition void Callback(const bool result) { std::cout << "Callback called! Result: " << result << std::endl; } int main() { // Register a callback using an existing function ProcessData(Callback); // Register a callback using lambda function ProcessData([](const bool result) { std::cout << "Lambda called! Result: " << result << std::endl; }); // Register using callable object CallbackType cb = [](const bool result){ std::cout << "Callable called! Result: " << result << std::endl; }; ProcessData(cb); }  ( 3 min )

In the world of keyboards, the WASD keycaps hold a special place. These four simple letters—W, A, S, and D—are often seen as the backbone of gaming. For most gamers, they’re more than just letters on a keyboard; they’re the foundation for movement in the virtual worlds they explore. But like all great inventions, the history of WASD keycaps goes beyond their initial function, evolving to become a symbol of gaming culture and a feature beloved by enthusiasts. Let’s take a journey through time to uncover the origins, evolution, and significance of WASD keycaps. The WASD layout, used predominantly in first-person shooters (FPS) and other action games, has become almost synonymous with gaming itself. But where did it come from? Originally, keyboards were designed with the arrow keys or the num…  ( 6 min )

🔍 Introduction JavaScript is packed with powerful features—but many developers stick to the basics and miss out on time-saving gems. In this post, I’ll show you 7 underrated tricks that can simplify your code, enhance readability, and make you look like a JavaScript pro in 2025. ?. const username = user?.profile?.name || 'Anonymous'; ✅ Avoids errors when deeply nested properties are undefined. Cleaner and safer than long logical chains. ?? const count = inputValue ?? 0; ✅ Returns default only if the left-hand value is null or undefined (unlike ||, which includes 0 or ''). const { title: blogTitle } = post; ✅ Grab and rename properties in one line. const isAvailable = !!value; ✅ Quickly turn any truthy/falsy value into a clean true or false. const user = { name, age }; // same as { name: name, age: age } ✅ Reduces repetition when property and variable names match. const key = 'theme'; const settings = { [key]: 'dark' }; ✅ Build flexible objects based on runtime values. const status = `You are ${loggedIn ? 'logged in' : 'logged out'}.`; ✅ Great for short conditional strings and UI feedback. These tricks may be small, but they add up to cleaner, more elegant JavaScript code. Whether you're working on a side project, fixing bugs, or building production apps—mastering these patterns will level up your skills. ✅ Try using at least 2 of these in your next app! 💬 Got a trick of your own?

Short answer: yes Over the past 5 years, I've learned a lot about communities. I've made many mistakes: I could probably create a 'Community Mistakes 101' crash course! Unfortunately, they didn't teach that in high school, which would have been useful. I learned that a community absolutely must have a specific goal. I also learned that while having an open community is good at the beginning, it becomes nearly impossible to handle and moderate long-term unless you dedicate an insane amount of time to it (trust me, I tried) or you are a bored millionaire lying on the couch all day (which is not my case). Regarding promotion, I've made the mistake in the past of overpromoting communities I created, simply because I was overjoyed about the new adventure. I now think this approach is wrong. it's better if people discover the community on their own. But now I really feel I am ready to do it right. So, why am I writing this? The reason is simple: I've just a new community, and I've decided to use Twitter (sorry, X) for it. The goal is to introduce curious developers to the Rust programming language and help them understand as much as possible. Joining this community is free, just request to join.

When trying to SSH into a newly created Linux server, you might run into a common error like this: $ ssh user@your-server-ip The authenticity of host 'your-server-ip' can't be established. ED25519 key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Any other names do not know this key. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'your-server-ip' (ED25519) to the list of known hosts. user@your-server-ip: Permission denied (publickey). This error simply means: “SSH couldn’t find a valid key to authenticate you.” ✅ What Actually Worked ssh ubuntu@your-server-ip You used the correct approach by providing the private key file: ssh -i /path/to/your-key.pem ubuntu@your-server-ip And this worked — because the server was expecting authentication via a specific private key (.pem file), not a default key from ~/.ssh/id_rsa. 🔍 Why This Happens key-based authentication only for better security. When you create a VM or instance, you’re often required to either: Upload your public key, or Download a .pem file that matches the server's authorized key If you try to SSH without specifying the .pem file, the SSH client defaults to using standard key files like ~/.ssh/id_rsa, which likely don’t match what the server expects. 🛠️ How to Avoid This in the Future Always specify the key manually with -i OR Add the key to your SSH agent so it's picked up automatically: ssh-add /path/to/your-key.pem 🧠 Pro Tip chmod 600 your-key.pem This keeps your key file secure and prevents SSH from refusing to use it.  ( 3 min )

When working with C++ and interfacing with API functions, developers often encounter the challenge of passing large blocks of data. In your case, you're constructing a large string using std::ostringstream and need to send this data to an API function, API_function, defined as int API_function(const char* data, int len). The issue arises when the data contains null bytes (0x00), resulting in data truncation. Let’s address how to pass this std::ostringstream payload effectively to the API function without copying it, especially in the context of constrained environments like microcontrollers. Understanding the Issue with Null Bytes The problem you're facing is due to the way C-strings (null-terminated strings) work in C++. When you use payload.str().c_str(), you get a pointer to the interna…  ( 5 min )

Hi everyone, The game is called BrainsIAAndPixels: it's going to be a 3D title with a pixel art style (even though it's set in a 3D environment), where NPCs won't be rigidly "scripted" but will instead be controlled by real artificial intelligence using pre-trained models running locally. The goal is to create a game where NPCs understand and react to what happens around them, rather than just following a fixed pattern. I'm using Python in Godot, and the AI part relies on ONNX models. Right now, I'm setting up the development environment, testing the AI integration, and building the foundations. The plot and genre aren't fully defined yet (I'm torn between survival, something narrative-driven, or similar), so any ideas are more than welcome. Thanks!  ( 3 min )

When working with object-oriented programming in Java, it's common to encounter situations where you want to pass a collection of objects from a subclass (child) to a method that expects a collection of objects from a superclass (parent). This might seem straightforward, but the compilation error you're facing highlights a key aspect of Java's type system, particularly with generics. Understanding Java Generics Generics in Java provide a way to specify a type parameter when defining classes and methods. When you declare a method that takes a list of a specific type, such as List, it expects a list that strictly contains Parent objects, not Child objects. Even though Child is a subclass of Parent, List is not considered a subtype of List. This is due to Java's type sa…  ( 5 min )

In Laravel projects or any large scale PHP application it's common to create helper files that contain reusable functions. These helpers make your code cleaner and more efficient. But there's a common issue, defining the same function more than once will cause a Fatal error.. What's the problem? If the same function is declared twice, PHP will throw an error like this: Fatal error: Cannot redeclare function_name() This often happens because of: Repeated includes: Package conflicts: The safe solution To prevent this issue, wrap your helper functions like this: if (!function_exists('sayHello')) { function sayHello() { return 'Hello!'; } } This way, if the function already exists, PHP will skip redefining it, and your app will keep running smoothly. In Laravel projects Even with Laravel’s powerful autoloading and service container, this pattern is essential. It keeps your project safe from unexpected conflicts and ensures maximum compatibility especially when working with custom helpers or external packages. Summary: function_exists It’s a small thing that can save you from big problems.  ( 3 min )

Introduction Integrating C++ functions with Lua can be a powerful way to enhance scripting capabilities in your applications. In this article, we will explore how to create a robust wrapper that allows Lua scripts to call various C++ functions seamlessly. This approach is particularly useful when re-using existing code without the need for an entirely new interface. Why Integrate Lua with C++? Using Lua as a scripting language provides flexibility and ease of use. The Lua C API allows you to register C/C++ functions that can be called directly from Lua scripts. This means that instead of creating new implementations of these functions for Lua, you can use your existing C++ functions, significantly reducing development time.

Two US senators are calling on Treasury Secretary Scott Bessent to “exercise [the department’s] authority” and change a provision affecting taxes on corporate holdings of digital assets. In a May 12 letter, Senators Cynthia Lummis and Bernie Moreno suggested Bessent had the authority to change the definition of “adjusted financial statement income” under existing US law in a way that could reduce what digital asset companies pay in taxes. The proposed adjustment was suggested as a way to modify a provision of the Inflation Reduction Act, signed into law in 2022. “Our edge in digital finance is at risk if US companies are taxed more than foreign competitors,” said Lummis in a May 13 X post.

According to Coinbase Canada's CEO, Lucas Matheson, the exchange is investing an undisclosed amount in Stablecorp and will help market its fiat-collateralized stablecoin, QCAD. “It’s really important that we have a stablecoin for Canadians,” Matheson told Cointelegraph in an exclusive interview on May 13, adding that stablecoins are especially urgent because the country has “no peer-to-peer [payment] rail” and “wire transfers cost $45 and take 45 minutes of paperwork.” “With stablecoins, 24/7, instant, borderless payments become possible — this is already feasible with existin…

Proponents of a bill to regulate stablecoins in the US Congress will likely take up another vote on the legislation in a matter of days without responding to concerns about President Donald Trump’s financial ties to the cryptocurrency industry. The Guiding and Establishing National Innovation for US Stablecoins, or GENIUS Act, failed to get enough votes to pass in the US Senate on May 8 amid calls from some Democratic lawmakers to halt any legislation related to digital assets until Republicans could address Trump’s potential conflicts of interest. Immediately following the vote, some lawmakers from both parties suggested they could reconsider the bill as early as this week, but without agreeing on a bipartisan path forward. After the GENIUS Act failed to proceed in a 48 to 49 vote in the…

Opinion by: Jupiter Zheng, Partner Liquid Fund at HashKey Capital Whenever Bitcoin falls in value, the narrative is always the same: It’s failing as a hedge against inflation. In the eyes of critics, Bitcoin is not the “digital gold” that so many others claim it to be. With gold hitting all-time highs, these critics have grown louder. If Bitcoin is an inflation hedge, they ask, why isn’t it also rallying as investors seek safety? Even in today’s bearish, high-inflation environment, the cardinal truth holds: Bitcoin is an inflation hedge — arguably the most important one for long-term capital preservation the world has seen.  Strength in scarcity Bitcoin has a hard cap of 21 million coins, with full circulation expected by 2140. This built-in scarcity mirrors gold, which has historically se…

The lawyer for a group of Caitlyn Jenner memecoin buyers said they will continue their legal fight against the ex-Olympian after a judge threw out the case for failing to adequately support the securities and fraud claims it brought. Jenner had escaped a class-action lawsuit from buyers of her self-titled memecoin, Caitlyn Jenner (JENNER) after California District Court Judge Stanley Blumenfeld Jr. said in a motion filed on May 9 that it was “sufficient to conclude that all nine causes of action are deficient” and sided with Jenner in dismissing the suit in its entirety for failure to state a claim. He allowed the class group to amend its suit, which must be filed by May 23, but warned it had “to be more focused and judiciously pleaded” than the original. A lawyer for the class group, Fitz…

A British High Court has issued a restraining order against computer scientist Craig Wright, preventing him from filing further defamation suits.  In a May 12 judgment, High Court Judge Edward Mellor said Wright’s repeated false claims and aggressive legal actions created legal “hell” for individuals and developers in the Bitcoin (BTC) community, adding that Wright sought to “weaponise legal systems” to intimidate and silence critics. His lawsuits forced people into costly and time-consuming legal defenses, often based on fabricated evidence, the judge added as he handed out a General Civil Restraint Order or injunction against Wright, prohibiting him from filing any more civil claims or applications in the High Court.  The court highlighted how this strategy was part of a pattern of abusi…

While Council’s Telegram cha…

Key takeaways: Bitcoin lags as investors shift toward stocks after the US and China strike a deal that could end the current trade war. Macroeconomic conditions are swinging away from gold investing and back to stocks.  Bitcoin (BTC) reached its highest price in over three months at $105,720 on May 12, but was unable to maintain its bullish momentum.

Opinion by: Robin Singh, CEO of Koinly Is there a catch for Bitcoin hodlers, with the asset’s price up over 600,000% since the beginning of 2013?  Perhaps — if governments keep waking up to Bitcoin’s value, the whole “you only pay tax when you sell” mantra could soon be a thing of the past. What if a wealth tax is the answer for revenue-hungry tax agencies with no time to lose? It’s a yearly tax on a person’s total net worth — cash, investments, property and other assets — minus any debts, applied whether or not those assets are sold or generating income. The idea is to boost public revenue and curb inequality, mainly by taxing the ultra-rich. A wealth tax takes a clip off what you own, not what you earn.

A 90-day tariff agreement between the US and China may set the stage for a broader recovery of stock and cryptocurrency markets, as investors look ahead to a potential tax relief package. The White House announced on May 12 that the two countries will reduce their respective tariffs to 10% for an initial 90-day period beginning May 14 — a 24% cut from current levels. Speaking at a press conference in Geneva, US Treasury Secretary Scott Bessent said both governments are aligned on avoiding further economic decoupling. “The consensus from both delegations is neither side wants to be decoupled,” Bessent said. “What has occurred with these very high tariffs was an equivalent of an embargo, and neither side wants that. We do want trade. We want more balance in trade.” Joint statement on US-…

Michael Saylor’s Strategy purchased a fresh batch of Bitcoin as the cryptocurrency pushed above $100,000 last week. Strategy acquired 13,390 Bitcoin (BTC) for $1.34 billion between May 5 and May 11, the firm announced in its filing with the US Securities and Exchange Commission published on May 12. The acquisition has increased Strategy’s total Bitcoin holdings by 2.4% to a total of 568,840 BTC, acquired for approximately $39.4 billion at an average price of $69,287 per coin.

Healthcare services provider KindlyMD merged with Bitcoin-native holding company Nakamoto Holdings to build a BTC treasury. According to a May 12 announcement, Nakamoto Holdings — a new company founded by David Bailey, a crypto adviser to US President Donald Trump — plans to build the first global network of Bitcoin (BTC) treasury companies in partnership with BTC Inc. Bailey said: “Traditional finance and Bitcoin-native markets are converging. The securitization of Bitcoin will redraw the world’s economic map. We believe a future is coming where every balance sheet – public or private – holds Bitcoin.” Long-term, the firm’s plan includes developing an ecosystem of Bitcoin-native companies, including media, advisory and financial services, all aiming to accelerate Bitcoin adoption and utility. The company resulting from the new merger aims to accumulate Bitcoin and grow the BTC held per share. Related: Trump crypto adviser David Bailey raises $300M for Bitcoin investment firm Not the first kid on the block Much like Michael Saylor’s Strategy (formerly MicroStrategy), Nakamoto Holdings plans to leverage equity, debt and other offerings to achieve its objectives.

What is RISC-V? RISC-V, pronounced “risk five,” is a modern open-source instruction set architecture (ISA) based on reduced instruction set computer (RISC) principles. In simple terms, it’s like a blueprint that defines a set of instructions that a processor can execute. RISC-V is designed to be highly modular, efficient and flexible. Originally developed by the University of California in 2010, the open-source framework gives developers the flexibility to tailor its functionality and use cases, plus offers cost savings compared to proprietary ISAs like ARM or x86. This offers a wide range of uses, from supercomputers to smartphones and now blockchains like Ethereum. On April 20, 2025, Ethereum co-founder Vitalik Buterin unveiled a “radical” new sc…

Social engineering in crypto, explained In the world of cryptocurrency, security goes beyond just protecting your wallet with a password or private key. One of the most deceptive and increasingly dangerous threats to crypto users today is social engineering. While you might think of cyberattacks as highly technical affairs, social engineering manipulates the most vulnerable aspect of security: human nature.  At its core, social engineering refers to the act of manipulating people into divulging confidential information or granting unauthorized access to systems.  Unlike traditional hacking, which typically exploits technological vulnerabilities, social engineering targets the human element. Attackers rely on deception, psychological manipulation an…

Key takeaways Though Bitcoin doesn’t support native staking, holders can earn yield through centralized lending platforms, Wrapped Bitcoin (WBTC) on Ethereum, and Bitcoin-related networks like Babylon and Stacks. WBTC allows BTC holders to participate in lending, liquidity pools and yield farming on Ethereum-based DeFi platforms like Aave and Curve but introduces bridge and smart contract risks. Protocols like Babylon and Stacks use mechanisms like native time-locked scripts or stacking to offer rewards without removing BTC from the Bitcoin blockchain. Custodial, smart contract and regulatory risks persist. Bitcoin’s community also remains divided on whether Bitcoin yield generation features align with its decentralized and trust-minimized ethos. Unlike proof-of-stake (PoS) blockchain…

US federal prosecutors have rebutted claims they suppressed evidence in their case against the co-founders of the crypto mixing service Samourai Wallet, arguing their disclosure of a conversation with Treasury Department staff was made within the required timeframes.  In a May 9 letter to a Manhattan federal court, prosecutors opposed a request for a hearing, claiming they handed over “all known substantive communications” between them and the Treasury’s Financial Crimes Enforcement Network (FinCEN) regarding Samourai “months in advance of pretrial motions and trial.” “The defendants will have seven months to make use of the information before trial,” they wrote. “Nothing more is warranted.” On May 5, Samourai co-founders Keonne Rodriguez and William Hill asked the court for a hearing, cla…

Crypto users could be looking for a more sustainable yield this cycle, as total value locked in decentralized finance (DeFi) lending continues to hit new highs while decentralized exchanges (DEXs) have lagged in comparison. DeFi lending protocols are currently the leading DeFi vertical in TVL at $53.6 billion, representing 43% of the $124.6 billion locked across all DeFi protocols.

Three teenagers have been accused of kidnapping a man at gunpoint after he was returning from a crypto event in Las Vegas, before driving him an hour outside of the city and robbing him of $4 million in crypto and non-fungible tokens. According to police, the incident occurred last November. The victim had finished hosting a crypto-related event in downtown Las Vegas, and when he returned home, the suspects forced him into a vehicle and drove him to a remote desert area an hour away from the city.  There, they forced him to hand over passwords to his accounts, according to a May 10 report from Las Vegas local news outlet 8 News Now.  The man was allegedly told to comply with the teens’ demands if he wanted to “live to see another day,” and because they also “had his dad and would kill him,…

Bitcoin’s potential price reaction to a trade deal between the United States and China could give insights into whether Bitcoin is being used as a safe-haven asset in the current market. Bitcoin (BTC) outperformed stocks and held up “incredibly strong” during a sharp sell-off on stock markets in April, following Donald Trump’s announcement of tariffs on “Liberation Day,” observed crypto trader “Daan Crypto” on May 11. Following its plunge to $75,000 on April 7, Bitcoin recovered strongly to trade 27% higher at around $95,000 by the end of the month. Meanwhile, indexes like the S&P 500 and Nasdaq declined in April.  At the time, people wondered if Bitcoin’s relative strength came from the narrative that countries were using Bitcoin to bypass tariffs. The analyst said the opposite should th…

Tinian, a small island in the US territory of the Northern Mariana Islands, could get a second chance at launching a stablecoin after the territory’s Senate voted to override the governor’s earlier veto of its stablecoin bill. On May 9, the Northern Mariana Islands Senate voted 7-1 to override Governor Arnold Palacios' April 11 veto of the bill, which would allow the Tinian local government to issue licenses to internet casinos and includes a provision for the Tinian treasurer to issue, manage and redeem a “Tinian Stable Token.”  The bill will now head to the 20-member Northern Mariana Islands House, which will need a two-thirds majority vote to override the veto and pass the bill into law. If the House is quick to pass the bill, the Tinian government could be in the lead for the first US …

Censorship-resistant “dark stablecoins” could come in increasing demand as governments tighten their oversight of the industry.  Stablecoins have been used for various groups to store assets due to a lack of government interference; however, with regulations pending, that could soon change, Ki Young Ju, CEO of crypto analytics firm CryptoQuant, said in a May 11 X post. “Soon, any stablecoin issued by a country could face strict govt regulation, similar to traditional banks. Transfers might automatically trigger tax collection through smart contracts, and wallets could be frozen or require paperwork based on government rules,” he said. “People who used stablecoins for big international transfers might start looking for censorship-resistant dark stablecoins instead.” On the heels of US Presi…

Hardware wallet provider Ledger has confirmed its Discord server is secure again after an attacker compromised a moderator’s account to post scam links on May 11 to trick users into revealing their seed phrases on a third-party website. “One of our contracted moderators had their account compromised, which allowed a malicious bot to post scam links in one channel,” Ledger team member Quintin Boatwright wrote on the Ledger Discord server.  “The issue was quickly contained: the compromised account was removed, the bot was deleted, the website was reported, and all relevant permissions were reviewed and secured.” Some members in Ledger’s Discord channel claimed the attacker abused moderator privileges to ban and mute them as they tried to report the breach, possibly slowing Ledger’s reaction.…

Introduction If you're delving into zero-knowledge proofs using Next.js and you've stumbled upon an issue generating zk-proofs, you’re not alone. Many developers encounter challenges when attempting to create zk-proofs with tools like snarkjs. This guide explores a common problem regarding input discrepancies that lead to proof generation failures even when everything seems correct. We'll dive deep into why this might be happening and how to effectively address it. Understanding ZK-Proofs and snarkjs Zero-knowledge proofs (ZKPs) allow one party to prove to another that they know a value without revealing the value itself. The snarkjs library is a popular choice for handling zk-proof generation in JavaScript. It is based on efficient cryptographic schemes, enabling developers to solve com…  ( 5 min )

Let’s be honest: most cloud “strategies” I come across aren’t really strategies — they’re glorified lift-and-shifts. On paper, migrating to the cloud promises flexibility, scalability, and cost savings. But in reality? Many organizations just copy their on-prem setup into AWS, Azure, or GCP — and call it done. As someone who’s spent years helping companies build scalable, secure, and cloud-native infrastructure across multi-cloud environments, I’ve seen this mistake over and over.

Finding common items between two generic lists in C# can be a common requirement in many applications, particularly when you want to understand overlaps in datasets. Using the example provided, we will discover how to efficiently identify shared elements between two lists of strings: Understanding the Problem In this scenario, we have two generic lists: List TestList1 = new List(); List TestList2 = new List(); TestList1.Add("1"); TestList1.Add("2"); TestList1.Add("3"); TestList2.Add("3"); TestList2.Add("4"); TestList2.Add("5"); Our goal is to find the common elements in TestList1 and TestList2, which, in this case, should return "3". Efficient Methods to Find Common Items When it comes to finding common elements between two lists, performance is critical, e…  ( 4 min )

Solana and Ethereum are two of the most popular blockchains in the world. But if you look under the hood, you’ll notice they speak different “languages.” Ethereum uses Solidity, while Solana uses Rust. So… what’s the difference? And why does it matter? Let’s break it down in plain English. Think of Solidity and Rust like languages people use to build apps — just like websites are built with HTML or JavaScript. Solidity was created specifically for blockchains — especially Ethereum. It’s simple, beginner-friendly, and looks a bit like JavaScript. Rust is more like the serious, high-performance cousin. It’s used to build powerful software like games, browsers, and now — Solana. One of the biggest problems in crypto? Bugs and hacks. Solidity, while easier to use, has been behind many major De…  ( 4 min )

What is a Laravel Observer? Observers in Laravel are used to listen for specific events on Eloquent models, such as creating, updating, and deleting records. The main advantage of using them is the ability to delegate the data handling logic to a dedicated class, keeping controllers and models leaner. Imagine you need to perform an action every time a user is created. Instead of writing that logic directly in the controller or the model, you can use an Observer to ensure that the logic is isolated and easier to test. Creating an Observer in Laravel is very simple. Let's take a look at a basic example of an Observer for a User model: php artisan make:observer UserObserver --model=User Open the App\Providers\EventServiceProvider file and register the observer: public function boot() { …  ( 4 min )

I'm thinking about starting a podcast with @blumen where we interview a bunch of somewhat successful / living-their-livelihoods-off-of-music people we went to music school with, and see where they are today. Basically Celebrity Catch Up: Life After I Did That Thing but without the Celebrity and without The Thing. 😬 Typing it out now makes it seem like a pretty bad idea, but I think it could be good information gathering for anyone considering music school or working in music. Plus, it would be amusing for our little cohort of music school grads and a fun way for us to reconnect with some folks. According to music-colleges.com (lol), SUNY Fredonia's music program ranks at #276 (out of 1451 schools they evaluated, so technically in the 20%!!). I imagine a podcast like this about Julliard grads would be much more successful, but those people probably wouldn't have good advice or relatable stories for real, non-prodigious but competent musicians. So far our initial brainstorm has us landing around: 30-45 min max Asking people about: What they studied How much schooling they ended up getting Their most memorable Fredonia experience What they do now Career highlights Career lows How much money they currently make (from music) What their advice would be for anyone pursuing their current career, or the program they studied in school Thoughts?  ( 3 min )

The Editor as a Storyteller: Crafting Meaning Through Cuts Film editing is far more than a technical exercise in arranging images; it is a profound act of storytelling. The editor shapes narrative, rhythm, emotion, and even truth by deciding what the audience sees—and when they see it. This power to construct meaning through selection and sequencing makes the editor an essential co-author of a film’s emotional and intellectual impact. At its core, editing transforms raw footage into a coherent and resonant experience. Through choices in duration, order, and juxtaposition, editors influence how characters are perceived, how themes develop, and how a story unfolds. The emotional arc of a scene—whether tranquil or intense—often hinges more on the cut than the shot itself. Editing allows a f…  ( 6 min )

Have you ever wondered how JavaScript functions can "remember" things even after they've finished running? That’s the magic of closures, and today we’ll break it down with a simple use case: building a custom counter function. We’ll touch on key concepts like function factories and state persistence to bring this idea home. Closures: For example, in our counter, a variable count is defined inside makeCounter(). The inner function (the actual counter) uses this variable. Thanks to the closure, the count is not lost when makeCounter() finishes, the counter function still remembers it. Function Factory: One Function, Many Counters Think of makeCounter() as a factory. Every time you call it, it gives you a brand new counter, like a fresh instance with its own private count. Each counter is completely independent. State That Sticks(State Persistence) The beauty of closures is state persistence. Since count is part of the closed-over scope, it keeps its value between function calls. That’s what allows the returned function to keep incrementing the same number, step by step. The key takeaway: even though makeCounter() is finished, the returned function still has access to everything defined inside it. That’s the closure in action, enabling encapsulation, memory, and a clean way to manage state without global variables. Closures aren’t just cool, they’re powerful. Once you understand them, you’ll start seeing them everywhere in JavaScript. And best of all, they make patterns like private counters, once complex, totally natural.  ( 3 min )

If you're building a product as a solo dev or part of a small team, you've probably struggled with design. You open Figma. You pick a font. Then a color palette. Then you browse some Dribbble shots. Then you go down a dark hole of animations, blur effects, neumorphism... and suddenly you've spent three hours tweaking gradients but your product still doesn't feel right. Here's the problem: you're thinking about design backwards. Design isn't about how your app looks. It's about what it lets people do and how easily they can do it. That's why I follow a dead simple rule: Design functionality first. Make it beautiful later. Design isn't about how something looks it's about what it lets people do. When you focus on visual details too early, you're decorating an idea that hasn't even proven its…  ( 5 min )

Hi DEV community! My name is Jo. I am a Digital Designer and Learning Technologist at the University of Leeds with a specialism in UX design and web accessibility. My coding journey started over lockdown when I completed a coding bootcamp with The Coders Guild, learning HTML, CSS, basic JavaScript, bootstrap, and Git. I will be honest, I don't need to use it every day for my career so I did forget some of what I've learnt since then but I have started to pick it back up again! My background is in graphic design so I hope to utilise my knowledge in this field to create more visually stunning web experiences. Currently with the support of my colleague, I help create bespoke web development projects that supplement the learning within our online course portfolio. For me personally, these projects are very basic (and partly supported by ChatGPT) because I am still learning... but I hope to change that! My goal is get to the point where I am much better and more confident in my skills at front-end web development and require less hand-holding. I also want to create diverse interactive experiences to hopefully foster genuine curiosity for the subject matter with our students and engage them with the learning material. Managers are more interested in boosting the reputation of the university, but the most important thing for me is to promote academia and make learning fun! Most of my posts will be misc stuff I've learnt and will probably be written with bad or inefficient code rather than being effective tutorials so please read with caution! Thank you for coming on this coding journey with me! If you'd like to connect, my LinkedIn profile is linked before (I no longer use any other social media platform anymore for my professional presence).

When working with Python and Bash scripts, logging output can become cumbersome, especially when you want to preserve the chronological order of the messages. The challenge you’re facing is that output from your Bash script is appearing in the log file before the output from your Python script due to buffering issues. This article will guide you through the best practices for ensuring that all outputs are recorded in the correct order, using file descriptors effectively. Understanding Output Buffering When Python writes output to a log file, it may use buffering, meaning it collects a certain amount of data before writing to the file. Similarly, Bash scripts can exhibit this behavior as well. When subprocesses are called within Python, outputs can arrive in an unpredictable sequence, there…  ( 5 min )

Back in 2022, my team and I were working on a service which was printing a fairly sizeable amount of logs from a distributed cluster of 20+ hosts: about 2-3 million log messages per hour in total. We were using Graylog, and querying those logs for an hour was taking no more than 1-3 seconds, so it was pretty quick. Infra people hated Graylog though, since it required some annoying maintenance from them, and so at some point the decision was made to switch to Splunk instead. And when Splunk was finally rolled out, I had to find out that it was incredibly, ridiculously slow. Honestly, looking at it, I don't quite understand how they are even selling it. If you've used Splunk, you might know that it has two modes: “Smart” and “Fast”. In “Smart” mode, the same query for an hour of logs was tak…  ( 4 min )

I've just released git-gpt-commit v0.9.0 — a Git extension that uses OpenAI's GPT models to automatically generate commit messages via the git gpt commit command. The default model has been upgraded to OpenAI’s GPT-4o. blazing-fast response speed (about twice as fast as GPT-4.1), allowing it to generate commit messages in an instant. very cost-efficient, at half the price of GPT-4-turbo. Previously, only English was supported. Now, with: git gpt lang You can choose from 12 languages for your commit messages: Previously, there was no option to add prefixes to your commits. Now, with: git gpt prefix You can toggle the inclusion of commit prefixes like feat:, fix:, or refactor:. Previously, you had to write your API key in a .env file in your project directory. Now, with: git gpt open-api-key You can now safely add and manage your OpenAI API key directly from the CLI. .env method is still supported as well. git gpt config You can now view all your current settings at once. Once installed, start by registering your OpenAI API key using the command above. Then, just stage your changes with git add, and run: git gpt commit The tool will analyze the staged changes, send them to the GPT model, and generate a context-aware commit message. You’ll need an OpenAI API key. npm install -g @laststance/git-gpt-commit While IDEs like VSCode and Cursor offer AI-assisted commit message generation, I couldn’t find a CLI tool that does the same — and that’s where I spend most of my time working with Git. Most of the features I personally wanted are now implemented, so I’m pretty happy with this release. Links: GitHub｜npm  ( 4 min )

In this problem, you're given a matrix of integers where each row and each column is sorted in ascending order. The goal is to find the index of the row that contains a specific target value. If the target value is not found in the matrix, return None. This is a common matrix problem that can be solved efficiently by taking advantage of the sorted structure. Instead of checking each cell (which would take O(n × m) time), you can reduce the complexity to O(n + m), where n is the number of rows and m is the number of columns. We make use of the matrix's properties—namely that values increase as we move right and down, and decrease as we move left and up. Start from the top-right corner of the matrix. Use a loop to traverse the matrix: If the current value equals the target, return the current row index. If the current value is greater than the target, move left. If the current value is less than the target, move down. If the loop completes without finding the target, return None. def find_row_with_target(matrix, target): if not matrix or not matrix[0]: return None # Matrix is empty n = len(matrix) # Number of rows m = len(matrix[0]) # Number of columns # Start at the top-right corner row, col = 0, m - 1 while row = 0: if matrix[row][col] == target: return row # Target found elif matrix[row][col] > target: col -= 1 # Move left else: row += 1 # Move down return None # Target not found matrix = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12] ] print(find_row_with_target(matrix, 7)) # Output: 1 print(find_row_with_target(matrix, 13)) # Output: None This solution demonstrates how understanding data structure properties can lead to more efficient algorithms. Instead of brute-force search, a directional approach through the matrix takes full advantage of the sorted nature, resulting in a linear time complexity relative to the dimensions of the matrix.  ( 4 min )

Hey folks 👋 Over the past few months, I’ve been curating a large collection of interesting and useful GitHub repositories — projects that show up on Hacker News, Reddit, Twitter, or deep in GitHub itself. I’ve finally compiled over 7,000 repositories into a single browsable database. 🌐 Check it out here: The Internet Cafe It’s organized in a Notion-style format, categorized and searchable. I'm planning to keep updating and improving it over time, possibly adding filters, tags, and maybe an API if there's demand. 🧠 Why I built it: I wanted a personal archive of inspiring open-source projects. Hacker News has gems that disappear after a day. I figured others might benefit from the same archive. 📣 I’d love to hear your feedback — whether it’s about the format, usefulness, or features you'd like to see added. Let me know what you think — and feel free to share it if you think others might find it useful. Cheers!  ( 3 min )

In this article, we’ll explore how to effectively connect to a server running on an Android emulator using the Angel framework on Flutter. Understanding the Issue Typically, access to a server running on localhost from an Android emulator is straightforward when you're trying to connect to your computer from within the emulator. However, the reverse – reaching into the emulator from an external browser – involves a different set of parameters. The Flutter framework, especially with the Angel backend, r…  ( 4 min )

C++ has been a cornerstone of performance-critical software for decades, powering everything from embedded systems to high-frequency trading platforms. Its ability to blend low-level control with high-level abstractions makes it uniquely suited for applications where every microsecond counts. As the language evolves, new standards like C++23 and the forthcoming C++26 introduce features that enhance both performance and developer productivity, particularly in the realm of high-performance services—systems requiring low latency, high throughput, and efficient resource utilization, such as real-time analytics, game servers, or distributed databases.

Slow queries can quietly erode performance, which frustrates users and strains your system. Fortunately, MySQL offers EXPLAIN, a diagnostic tool that reveals how your queries execute. Think of it as a window into your database engine’s decision-making process. With EXPLAIN, you can figure out exactly why a query is underperforming. Maybe it’s looking at too many rows, ignoring indexes, or struggling with joins. This understanding is key for developers and database administrators who are aiming to optimize performance. To use EXPLAIN, simply place it before your query. It works with SELECT, INSERT, UPDATE, or DELETE statements. For instance: EXPLAIN SELECT name, email FROM customers WHERE age > 30; This will return the query execution plan in table format. +----+-------------+-----------+…  ( 8 min )

As someone who's been working as an Ab Initio developer, I’ve had a front-row seat to a reality that many in the data world seem to overlook: Most of the features that big data platforms like Hadoop or Spark introduced as “innovative” already existed — and were mature — in Ab Initio long before they became industry buzzwords. This post isn’t about fanboyism. It’s a perspective from someone who’s seen the nuts and bolts of how real enterprise-scale data processing works, and how underappreciated Ab Initio really is. Partitioning in Hadoop? Great. But Ab Initio had it long before the big data wave hit. The platform's Co>Operating System supports native massively parallel processing (MPP), with built-in strategies like: Round-robin partitioning Key-based partitioning Broadcast or replicated p…  ( 4 min )

Introduction When working with Jest in a TypeScript environment, particularly with mocked functions, you may encounter issues where one test affects another. This problem often arises when mocking is not properly reset, leading to test interference. In this article, we’ll explore why this side effect occurs and provide you with effective solutions, especially in your example involving test cases for the loginPagePresenter. Understanding the Side Effect In your case, the issue stems from the way Jest mocks the apiGateway.post function. When one test modifies the mocked implementation but fails to reset it afterward, it can inadvertently influence subsequent tests. Jest mocks maintain their state across tests unless specified otherwise. This can lead to unexpected results, especially in scen…  ( 4 min )

The common approach to using sprite sheets involves applying CSS classes with pre-calculated coordinates to control the positioning within the sheet. This typically relies on background-image, which does not natively support features like alt text or lazy loading that come built-in with elements. Additionally, using can improve accessibility and semantics depending on how the image is used. This approach builds upon an article on css-tricks, and expands it by introducing scaling of the individual sprites. Skip to Codepen Demo object-fit: none and object-position: x y allow us to select specific areas of an image which is the basis of this idea. The object-position values need to be pre-calculated, just like in the class-based approach. This could be stored as an object literal…  ( 5 min )

JavaScript isn't broken — but if you've ever wondered why a variable returns undefined or a function throws an error before it's even called... you're not alone. Many developers hit weird bugs due to scope and hoisting without realizing what's really going on. I just dropped a post that breaks down: Why var, let, and const behave so differently How JavaScript really handles function and block scopes What hoisting actually does (and doesn’t) How to write bug-free, predictable code If you've ever thought “JavaScript makes no sense”, this post is for you. 👉 I wrote the full breakdown here: Understanding JavaScript Scope and Hoisting: A Beginner to Intermediate Guide  ( 3 min )

** **A JavaScript engine is the core software component that executes JavaScript code, typically as part of a web browser or runtime. Modern engines are highly optimized and use Just-In-Time (JIT) compilation to improve performance . For example, Google’s V8 engine (written in C++) drives Chrome and Node.js, while SpiderMonkey runs in Firefox, JavaScriptCore in Safari, Chakra in (legacy) Edge, and Hermes in React Native. Each engine implements the ECMAScript standard (the formal spec for JavaScript) and often also supports WebAssembly execution in the same sandbox . This means JavaScript engines are critical for making web pages responsive and fast, and even power serverside Node.js apps and desktop frameworks like Electron . How JavaScript Engines Work JavaScript engines transform source …  ( 9 min )

Introduction In traditional software development, testing often occurs late in the cycle, leading to bottlenecks and delayed releases. Left-shift testing is a proactive approach where testing activities are introduced earlier in the development lifecycle. While automation is often associated with left-shift testing, manual QA testers can also play a crucial role in implementing this strategy—especially in frontend development. This article explores how manual QA testers can adopt left-shift testing principles to improve frontend quality, reduce defects, and accelerate delivery. Left-shift testing means shifting testing activities left (earlier) in the software development lifecycle (SDLC). Instead of waiting for a fully developed feature, testers engage early in requirements, design,…  ( 5 min )

For a SaaS (Software as a Service) product, choosing between MySQL and MongoDB depends heavily on the type of data, scalability needs, and how the app works. Use Case Recommendation Traditional SaaS (multi-tenant, structured data, relational) ✅ MySQL Flexible, unstructured, dynamic data (e.g., user-generated content, document-heavy) ✅ MongoDB Feature MySQL (Relational) MongoDB (NoSQL Document) Data Structure Tables, Rows, Foreign Keys (SQL) JSON-like Documents (BSON) Schema Fixed schema (strong structure) Schema-less (flexible) Joins & Relationships Native support Complex joins are harder Transactions Strong ACID support ACID (limited or requires special setup) Scalability Vertical + Read replicas Easily horizontally scalable Performance Great for complex queries, joins Fast for large, flexible datasets Multi-Tenancy Support Very strong (tenant per row, schema, DB) Requires thoughtful design MySQL: SaaS with complex relational data (users, roles, payments, subscriptions). Requires data integrity and transactions (e.g., financial systems). Example: B2B CRM, ERP, Invoicing software. Strong multi-tenant support using shared schema with tenant_id. MongoDB: SaaS with highly dynamic or nested data, like CMS or analytics dashboards. You don’t rely heavily on relationships or joins. You need to store flexible documents per user. Faster iterations and schema evolution. SaaS Type Best DB Project Management Tool (tasks, users, teams) ✅ MySQL CMS/Blog Platform ✅ MongoDB Analytics or IoT Dashboard ✅ MongoDB Accounting / Billing SaaS ✅ MySQL Chat/Messaging SaaS ✅ MongoDB (with Redis/Cache) Some large SaaS companies use both: MySQL for core user/accounts/transactions. MongoDB or ElasticSearch for logs, analytics, unstructured content. If you are: Building a structured SaaS with users, payments, plans, etc. → go with MySQL Building a dynamic content-based platform or analytics service → go with MongoDB  ( 3 min )

When working with JWT authentication in C#, you might encounter a common issue: the token signature validation fails due to a missing 'kid' (Key ID) in the header. This issue often surfaces when using the HS256 algorithm without a kid component, particularly when your token is validated against a set of keys that do not match. Understanding JWT Tokens and Signature Validation JWT (JSON Web Token) is a widely used token format for secure communication between parties. A JWT typically consists of three parts: header, payload, and signature. The header contains information about how the token is signed, including its algorithm and, optionally, a 'kid' if multiple signing keys are involved. In situations where the 'kid' is missing, the application may not be able to match the signing key prope…  ( 4 min )

“An icy visitor flames out in dramatic fashion”– Sean Walker A comet is a small icy object that orbits the Sun. It’s made of dust, rock, and frozen gases (like water ice, carbon dioxide, and more). I’m sure that everyone’s familiar with this definition of a comet, but today we’re not talking about comets in general but a specific one — ATLAS! Comet ATLAS or C/2024 G3 was named after ATLAS- Asteroid Terrestrial-impact Last Alert System, which was the first to discover it. Comet ATLAS was a 19th-magnitude object. To explain, the magnitude of an object measures its brightness. The brighter the object the lower the number. The comet is also described as having a diffuse coma and a short tail. A coma is a cloud of gas and dust that forms around the nucleus of a comet upon receiving heat from th…  ( 4 min )

In Java, file reading and writing can be done efficiently using buffered streams, readers, and writers. Here's a short explanation with examples: 1. Buffered File Reading (Using BufferedReader) Buffers data for efficient reading (instead of byte-by-byte). import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; public class ReadFile { public static void main(String[] args) { try (BufferedReader reader = new BufferedReader(new FileReader("file.txt"))) { String line; while ((line = reader.readLine()) != null) { // Reads line-by-line System.out.println(line); } } catch (IOException e) { e.printStackTrace(); } } } 2. Buffered File Writing (Using BufferedWriter) Buffers data for efficient writing. import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; public class WriteFile { public static void main(String[] args) { try (BufferedWriter writer = new BufferedWriter(new FileWriter("output.txt"))) { writer.write("Hello, Java!"); writer.newLine(); // Adds a newline } catch (IOException e) { e.printStackTrace(); } } } 3. Key Classes Class Purpose FileReader / FileWriter Reads/Writes characters (text files). BufferedReader / BufferedWriter Wraps readers/writers for buffered I/O. FileInputStream / FileOutputStream Reads/Writes bytes (binary files). Scanner Alternative for reading text (e.g., new Scanner(new File("file.txt"))). 4. Try-with-Resources Automatically closes files (no need for finally blocks). Used in the examples above (try (BufferedReader ...)). When to Use? Use BufferedReader/BufferedWriter for text files. Use FileInputStream/FileOutputStream for binary files (images, etc.). Use Scanner for parsing structured text. Let me know if you'd like a deeper explanation! 🚀  ( 3 min )

✅ Understanding the Goal You're being asked to implement a function called deepEqual(valueA, valueB) that checks if two values (which can be primitives, objects, or arrays) are deeply equal. The keyword here is deep, this means we can’t just check equality on the surface (like ===), especially for things like objects and arrays. We need to go into nested levels and check if all elements or properties match recursively. 🧠 Think Like This, Before you jump into code, ask yourself questions like: -> What types of values can valueA and valueB be? -> How do I handle primitive types vs arrays vs objects? -> What does it mean for arrays or objects to be “equal”? -> Should I use recursion? 🤔Design Your Thinking Strategy: Base case: If a === b, return true. Type check: If types differ, return false. If both are arrays: Check length. Recursively compare each element. If both are objects (but not arrays): Compare keys. Recursively compare each corresponding value. Otherwise: return false. 🔁 Why Recursion? Why Loops Alone Aren’t Enough? A simple for loop works great when you're comparing flat structures, like two arrays of numbers. But when the data can go many levels deep , arrays inside objects inside arrays, etc. you’d need: a loop inside a loop inside a loop... 😵 or a smarter approach that can handle any depth That’s Where Recursion Shines. Recursion is perfect for tree-like or nested structures, because you can say: “If the current level is an array or object, go deeper and run the same logic again.” So your function ends up being clean and adaptable to any depth. ⚡️Implementation of the deepEqual function using recursion: With a clear understanding of recursion and careful handling of data types, you now have a robust deepEqual function that can accurately compare even the most nested structures, a must-have tool in any JavaScript developer's toolkit.  ( 3 min )

At first glance, an ID might seem like the most boring part of your application. It's just a unique identifier, right? But if you're building systems that scale - across regions, across teams, across microservices - your ID generation strategy can be the silent hero or the hidden landmine. And that’s exactly why companies like Netflix, Twitter, Stripe, and Shopify have ditched traditional auto-incrementing IDs in favor of UUIDs and Snowflake-like systems. Let’s explore why UUIDs are not just random gibberish, but a critical architectural decision in high-scale systems - and what lessons we can steal from the giants. Auto-incrementing integers are deceptively simple and convenient. They work great when: You have a single database. You can guarantee a single source of truth. You're not worri…  ( 5 min )

When reading discussions about C++ variable definitions and their associated rules, it’s essential to understand the distinctions between variable definition, initialization, and assignment. Each concept plays a crucial role in how variables behave within C++ code, and knowing these differences can significantly enhance your programming efficiency. Let's delve deeper into variables in C++ and clarify these terms with examples. Understanding Variable Definition In C++, variable definition is the process of declaring a variable to let the compiler know the variable’s type and its name. For instance: int x; // Variable definition Here, int x; tells the compiler to reserve space in memory for an integer variable named x. However, at this point, x does not hold any value; it’s simply defined. …  ( 5 min )

Google is testing a new “Desktop View” mode in Android — and it’s more than just screen mirroring. We’re talking about taskbars, resizable windows, mouse support, and full-on multitasking. Basically, a PC layout powered by your phone. If this rolls out, it could mean you won’t need a Samsung device to get that DeX-style desktop experience. Hidden taskbar (like Windows or ChromeOS) Drag-and-drop between apps Resizable, windowed apps Smooth support for external monitors Mouse + keyboard ready It’s currently tucked away in Android beta builds, but signs suggest Google is moving fast with this. Samsung DeX gave us a glimpse of mobile desktop computing. But now Google is building something native — possibly for all Android phones. That means more freedom for users, especially those who want to work on the go with just a phone and a screen. This could shift how we think about smartphones in workspaces.

Written by Paul Akinyemi✏️ JavaScript date handling presents challenges that can impact application reliability. This guide examines native Date API capabilities alongside specialized libraries, providing practical examples and performance metrics to inform your implementation decisions. You'll learn when to use built-in methods versus external libraries, how to properly handle localization and time zones, and how to avoid common date-related pitfalls in your projects. Before formatting a date for display, you need to understand the format in which you receive it. Here are the three most common formats, each of which displays the same date and time: ISO 8601 strings (standardized and directly consumable by new Date()) — "2025-02-18T14:30:00.000Z" Unix timestamps (numeric representati…  ( 11 min )

Imagine you're trying to teach a child how to recognize fruits. You show them dozens of apples, bananas, and oranges, telling them the name of each fruit. Over time, the child learns to distinguish between them, even when they see new fruits for the first time. This, in a way, is what Machine Learning (ML) is all about—teaching machines to learn from data and make decisions or predictions without being explicitly programmed. 🧠 So, What Is Machine Learning? At its core, Machine Learning is the art and science of solving problems by learning from data. We start with a problem, gather data related to it, and then use algorithms to build a statistical model that can make sense of new, unseen data. But ML isn’t one-size-fits-all. There are several ways to teach a machine, depending on what k…  ( 4 min )

In the vast world of computer science, while the foundations and principles of algorithms remain consistent, the ways we approach, implement, and analyze them continue to evolve. Today, we’ll delve into a distinct implementation of the insertion sort algorithm and an innovative tool that simplifies its analysis, both brought to the fore by Fernando Pelliccioni. The provided algorithm, while rooted in the classic insertion sort paradigm, offers a twist — working its magic backward: `function insertion_sort_backward(f, l, r) { } function linear_insert_backward(c, l, r) { var s = sequence(array_descending(), "s", lt); print(s); Understanding an algorithm is one thing; seeing it in action is another. Fernando Pelliccioni introduces an insightful GUI tool for this very purpose: componentsprogramming.com/algorithms. This interactive platform not only animates the algorithm’s execution but also serves insights into memory sequences, variables, stack calls, and various operation statistics. A glimpse into the potential data output: n: 10 (Note: The above metrics are illustrative and may not reflect the actual values for specific runs.) While the foundational algorithms might be familiar territory, it’s the nuanced implementations and tools for deeper understanding that elevate our coding journeys. Fernando Pelliccioni’s distinct implementation of the insertion sort and the accompanying analysis tool stand as testaments to innovation in the world of algorithms. Whether you’re a programming veteran or a newcomer, the landscape of algorithms always promises fresh terrains to explore.  ( 4 min )

Dia 2 - Neurointerfaces — Como nosso cérebro enxerga o Frontend “Don't make me think.” — Steve Krug Essa frase virou um clássico do design de interfaces. E ela tem base neurocientífica: nosso cérebro evita ao máximo o esforço cognitivo desnecessário. Segundo a Teoria do Processamento Dual (Kahneman, 2011), o cérebro humano opera com dois sistemas: Sistema 1: rápido, automático, intuitivo. Sistema 2: lento, deliberado, requer esforço. Sempre que possível, o cérebro usa o Sistema 1 — e só ativa o 2 se for realmente necessário. Isso significa que interfaces que exigem leitura, análise ou adivinhação ativam o sistema mais lento — e geram frustração. Ícones sem legenda (usuário precisa adivinhar) Menus escondidos (hambúrguer, submenus profundos) Mudanças de padrão (ex: botão de "enviar" que parece um ícone) Elementos previsíveis e familiares Legendas claras Hierarquia visual forte Espaço em branco bem utilizado Estudos de eye-tracking (rastreio ocular) mostram que usuários criam um padrão de leitura em F na tela. Isso significa que eles escaneiam de cima para baixo e da esquerda para a direita — e ignoram o resto. Kahneman, D. (2011). Thinking, Fast and Slow. Krug, S. (2014). Don't Make Me Think, Revisited: A Common Sense Approach to Web Usability. Nielsen Norman Group (2006). F-Shaped Pattern For Reading Web Content. Essas obras explicam por que o design intuitivo funciona melhor: ele não força o cérebro a sair do “modo automático”. Reduza a necessidade de pensar. Use padrões comuns da web. Priorize clareza sobre criatividade. Não reinvente botões sem motivo. Dê pistas visuais. Ícones com texto, hierarquia, espaçamento. Teste com usuários reais. Se alguém hesita antes de clicar, sua interface não está clara o suficiente. Criar uma interface clara é um ato de empatia: você está poupando energia mental do seu usuário. Se ele entender o que fazer sem precisar pensar, você venceu. Qual interface você achou mais confusa recentemente? Comenta aqui e vamos analisar no próximo post da série! 👇  ( 4 min )

What if your design system didn't need to ship components in a component library? From an engineering standpoint, most of a design system's maintenance overhead is creating and shipping components for a specific framework coupled to a styling system of some kind. I've been asking the same thing on Medium. And then built a POC to see if it would work and made it available in Github. If using AI agents, component libraries break free of framework and style constraints by generating components at build time from prompts and generator functions. They're still driven by design through tokens and themes, but without prebuilt components. It gets even better when using RAG for distribution and documentation, eliminating tools like Storybook in favor of on-demand generation by AI agents using the system itself, not a collection of stories or API documentation.  ( 3 min )

Expanding your business through franchising can be a lucrative strategy, but it requires a solid legal foundation. At the heart of this foundation lies the Franchise Agreement—a legally binding contract that defines the relationship between the franchisor (the brand owner) and the franchisee (the investor or business partner). This agreement outlines the rights, responsibilities, and expectations of both parties, ensuring a harmonious and profitable partnership. A Franchise Agreement is a legal document that grants the franchisee the right to operate a business using the franchisor's brand, trademarks, business model, and support systems. In return, the franchisee agrees to operate the business according to the franchisor's established guidelines and pay agreed-upon fees. This agreement se…  ( 5 min )

Hey all, We recently started working on an API Client - Voiden - and wanted to share it here to get your thoughts and feedback. Over the past few years, we found ourselves managing way too many tools just to work with APIs: one for api specs, another for docs, a third for tests, etc etc. Eventually it starts to feel more like a performance than actual work. So we built Voiden: A git-native, extensible, and lightweight client that brings everything—specs, docs, tests, mocks—into one place. No bloat, no lock-in, no "platform overhead." Just structured API workflows that don’t fight your tools or your team. A few things we care about: -Reusability and composability : APIs as building blocks, not silos. -Structure over scatter : everything lives together in one workspace. -No sign-in required : you can use it without creating an account. Free and open — we are building this with the community in mind. Just to be clear: The goal is NOT to replace OpenAPI, but to provide a layer around existing specs that feels coherent, hackable, and friendly to real-world dev workflows. You can check it out here: https://voiden.md/ And if you have feedback, suggestions, or just want to follow along: https://github.com/VoidenHQ/feedback We are still early, but would love to hear what you think—what you like, what is missing. Appreciate any time you take to try it out. Nikolas  ( 3 min )

Introduction Can we store polymorphic objects by value in C++ STL containers? This topic often arises among C++ developers, particularly with the challenges posed by object slicing when dealing with base and derived classes. The crux of the issue lies in the behavior of STL containers and how they handle objects. In C++, when we store derived class instances in a container that holds base class objects by value, object slicing occurs, which results in the loss of the derived class-specific behaviour. This article aims to explore this concept specifically within the context of C++11 and later revisions, dissecting the challenges and potential approaches. Understanding the Slicing Problem When you store a derived class object in a container designed to hold objects of its base class by value…  ( 5 min )

🔐 Temporary credentials in AWS are powerful—but also widely misunderstood. They allow developers and systems to access AWS resources without relying on long-lived access keys. But just because they expire doesn’t mean they’re safe by default. In this post, I break down: ✅ When and why to use temporary credentials 🧱 Where things go wrong (over-permissive roles, lazy session durations…) 🔒 Best practices for keeping temp creds secure 🧠 Advanced use cases like federation and IAM Roles Anywhere I’ve seen real-world setups where: Temp credentials lasted 12 hours Were used with AdministratorAccess In CI/CD pipelines with no monitoring That defeats the whole point of ephemeral access. Should Be Doing 🔸 Use least privilege roles Scope your roles tightly and use IAM condition keys like aws:SourceIp. 🔸 Shorten session durations 15–30 minutes is more than enough for most automation tasks. 🔸 Log STS usage with CloudTrail Every AssumeRole or GetSessionToken should be traceable and alertable. 🔸 Require MFA where appropriate Especially for sensitive role assumptions—break-glass or prod access. 🔸 Automate responsibly Don’t reuse temporary creds or store them insecurely in config files. Use the SDKs properly. For non-AWS workloads (like on-prem apps), IAM Roles Anywhere lets you issue short-lived AWS credentials using signed certificates. It's a powerful addition for hybrid setups, but comes with its own set of guardrails.

The Mechanics of Humanization But how is this happening? Are all these people really transferring from talking to humans to talking to machines? What does the language model operate behind these AIs? In 2025, there is no ambiguity between talking and chat bots. It's framed mostly by instruction and subsequently, output. Of course, the ability for AI to talk like a human wasn't developed overnight either. Over the years, developments in large language processing models have created systems that operate on trillions of parameters - whereas previous iterations operated on mere billions. This difference of magnitude means that AI can better understand context, remember previous messages and conversations, and stay on task within one stream of consciousness across lengthier periods.

Structured Query Language (SQL) is an essential tool for working with databases, but even seasoned developers sometimes make mistakes that can lead to slow queries, inaccurate data, and inefficient systems. When summarizing data, the GROUP BY clause organizes information into meaningful groups. However, misusing GROUP BY can lead to incorrect results—sometimes without obvious errors. A database tracks employee salaries per department. Someone writes: sql To summarize salaries by department, the query should be: sql sql Only group necessary columns—non-grouped columns need aggregate functions. Use HAVING instead of WHERE for filtering grouped results: sql During testing, SELECT * is quick and handy. But in production? It slows queries, overloads networks, and makes applications harder to maintain. sql sql Explicitly specify needed columns instead of SELECT *. Use LIMIT for large queries: sql sql sql Indexes speed up data retrieval, but poorly designed indexes can slow down updates, inserts, and deletes. sql A better strategy: sql Index columns frequently used in WHERE clauses. Avoid over-indexing, which slows write operations. Use EXPLAIN or ANALYZE to check query performance: sql Use composite indexes only when queries filter by multiple columns: sql NULL values represent missing information, and if not handled correctly, they can cause errors or misleading results. This query calculates average salaries: sql Ensure NULLs are accounted for: sql sql Use IS NULL and IS NOT NULL to prevent logic errors. Replace NULLs using COALESCE() or IFNULL(): sql Validate NULL handling in reports to avoid misleading calculations. SQL mistakes can affect speed, accuracy, and system stability. But with the right practices, you can write efficient, optimized queries that scale well. GROUP BY must include all non-aggregated columns to avoid incorrect grouping. Never use SELECT * in production—fetch only required data. Index smartly, targeting commonly searched fields. Handle NULLs carefully, ensuring accurate calculations.  ( 4 min )

When I first thought about switching from Windows to Linux, the main reason was simple — I want to control my computer. ⚙️ I love to automate everything One of the main reasons I chose Linux is the ability to automate everything. Every update, every new package — I decide what and how to install. This isn’t tied to forced downloads like in Windows. This is my freedom. 🌍 A world of options Linux gives you a huge variety of distributions, each suited to different needs. It’s like a builder where you choose what you need: I started with Ubuntu, because it’s stable, user-friendly, and has good documentation. But now I’m getting more interested in Arch and Fedora. I’ve realized that in Linux, it’s easy to switch between distributions, migrate between them, and adapt the system to your needs. 💻 Tech and CTF My passion for CTF and cybersecurity gave me even more reasons to switch to Linux. This system provides me with the tools to work with security, set up virtual machines, create test environments, and perform various attacks. You can’t achieve that in Windows, not to the same extent. Linux is a system for people who not only want to use technology but also understand it from the inside. For me, it’s not just an operating system, it’s a tool for growth and self-expression. 🌟 My freedom After switching to Linux, I felt that I was finally in control of my system. It’s not just an OS, it’s an environment that allows me to build, optimize, and use my computer the way I need. 🚀 Final thoughts If you’re tired of your computer not being yours, try Linux. A system where you decide how everything works. Where you can customize everything, automate it, and learn. It doesn’t matter if you’re a beginner or an experienced user — Linux has something for everyone.

Summary WhatsApp imposes a 24-hour customer-service window during which you can send any message; outside of it, only template messages (unformatted) are allowed. Goalmatic.io needs to let users send richly formatted content (articles, poems, etc.), so we built a two-step workaround: Template Send: Strip formatting and send via a WhatsApp template. On-Click Upgrade: Include a “Get Formatted Text” button in the template. When the user clicks, the 24-hour window reopens, allowing us to send the original, fully formatted message. Below is an end-to-end example in Node.js using the WhatsApp Cloud API. WhatsApp’s customer-service window rules mean: Within 24 hours of a user message, you can send any content (text, media, formatted). After 24 hours, only template messages (unformatted, pre-app…  ( 5 min )

Introduction Troubleshooting errors effectively in your SwiftUI application can be challenging, especially when they aren't caught where you expect them to be. In this article, we will explore common pitfalls in error handling when dealing with a view model in SwiftUI. We will focus specifically on how to ensure that errors thrown from your view model can be gracefully handled at the view level. Understanding the Issue In Swift applications, especially those using SwiftUI, it can sometimes occur that errors that are thrown from a view model do not propagate to the view layer. This can lead to confusion as you may not see the expected error messages in your user interface. In your case, while the error logging from the network layer indicates that an error is being produced, the error isn't…  ( 5 min )

When developing web applications, storing data in the browser is essential for maintaining user sessions, saving preferences, and improving performance. Three common methods for client-side storage are Local Storage, Session Storage, and Cookies. While they serve similar purposes, they differ in data persistence, size limits, and accessibility. This article will explore the differences, advantages, and best use cases for each storage method. Local Storage is a browser-based storage mechanism that allows web applications to store key-value data persistently on the user’s device. The stored data does not expire and remains available even after users close and reopen the browser. ✔️ Persistent Data — Data is stored permanently until manually deleted // Storing data in Local Storage localStora…  ( 5 min )

Battling Loneliness in a Digital World: Ghosting Nowadays and AI Companions for Emotional Support When No One Else Is There for You Loneliness is an epidemic. Despite millions forged in digital connection, people feel lonelier than ever. By 2025, a growing number of studies have proven increasingly more distressingly. Ghosting is now a primary emotional component responsible for such heartache. Ghosting someone means cutting off all communication with them without offering an explanation. But could artificial intelligence save the day? Here's how AI chat companions revolutionize the fundamental game of emotional wellness. It's odd to be alive and alone during such a connected time.

Hey Devs! 👋 Yeah, I know… it’s been a while 😅 LearningTrackApp (name still under construction 😅) So this new app I’m building is a platform made for NGOs — specifically the ones that teach underprivileged kids. The idea is to help them keep track of their students’ progress, batch sessions, timings, names — basically everything important in one place. It’s simple, but I think it’s gonna be really useful. The app has a few different roles to keep everything organized: Super Admin – can access and manage all the NGOs. Admin – manages just their own NGO. Supervisor – the on-site person ensuring sessions are running smoothly. Volunteers – the awesome people who teach the kids. Students – well, this one explains itself 😄 That’s pretty much what I wanted to share for now. I genuinely feel like this app can be something impactful, and I’m excited to build it step by step. I’ll be posting more about the tech, my role, and the challenges I face in the next few posts. Until then, peace out ✌️  ( 3 min )

Breaking the Silence: How AI Companions Combat Loneliness in the Digital Age In a world where digital connections have paradoxically made us more isolated, loneliness has become a silent epidemic.

This growing crisis of disconnection demands innovative solutions, and AI chat technology is emerging as an unexpected but effective ally in the battle against emotional isolation. The modern loneliness paradox often begins with a familiar scenario - being ghosted. That moment when messages go unanswered, calls unreturned, and a person simply vanishes from your life without explanation. This form of rejection triggers profound emotional distress, leaving many feeling aba…  ( 6 min )

Combating Loneliness in 2025: AI Companions as Devices of Emotional Engagement Loneliness is a universal issue faced no matter where one resides on the globe. Yet, in 2025, after "ghosting" many find it harder to connect, and 2025 - filled with digitalized conversation and disconnection - is the year that so many feel rejected by unresponsive texts and calls; if one fails to respond, there exists no explanation.

De-Silosizing the Soul: How AI Companions Help Cure Loneliness in a Ghosting Technological World By 2025, loneliness is one of the most significant public health crises of our generation. As society advances and individuals are learning to communicate less and less in person, the notion of "ghosting" - the often irreversible, severance of once deep social connections without reciprocity or explanation - becomes an all too familiar reality. Unfortunately, when individuals are "ghosted," they oftentimes face emotional trauma with rumination on what they did to deserve such a departure from their existence. The growing concern of ghosting fosters quiet rooms where people question why no one wants to talk to them anymore. Yet, AI companion chatbots are helping combat the issue of loneliness …  ( 6 min )

In the world of programming, handling user input effectively is crucial, especially in Python where data types dictate how we manipulate the input. You've made an attempt at creating an age calculator, but you're running into issues with validating the age input.

Writing clean SQL is about more than just correctness—it's about clarity. SQL comments help you communicate with others (or your future self) by adding context, notes, or temporarily disabling code. Let’s explore how to use comments effectively. Using Comments in SQL Two Main Types: Single-line -- Pull users created in the last week SELECT * FROM users WHERE created_at >= CURRENT_DATE - INTERVAL '7 days'; Multi-line /* Use this version for reporting Includes only verified accounts */ SELECT * FROM accounts WHERE verified = TRUE; Why and When to Comment Helpful When: Writing complex logic Sharing scripts with a team Disabling old queries during testing Avoid: Leaving sensitive info Explaining simple queries Letting comments go stale Different Engines, Different Capabilities MySQL: Supports versioned comments /*! */. PostgreSQL: COMMENT ON lets you label schema elements. SQLite: Keeps it basic and portable. SQL Server & Oracle: Great for documenting stored code and schema. FAQ How do I add comments in SQL? Use -- for quick notes or /* */ for multiple lines or blocks. Yes—wrap code in /* */ and it won’t run. Yes, both styles are widely supported with small engine-specific features. Only if they include secrets or mislead developers. Keep them clean and relevant. Conclusion SQL comments don’t take much effort but make a big difference. They’re your best tool for writing collaborative, maintainable SQL scripts. Read SQL Comment: A Comprehensive Guide for more insights.  ( 17 min )

Overview, Historical Timeline, Problems & Solutions Python lets you use many characters to write programs. But some characters cannot appear in code unless they are part of a string or a comment. These are forbidden characters. @ $ ? Forbidden characters are printing ASCII characters that Python does not use in its grammar. If you write one outside a string or comment, Python will stop with a syntax error. Python raises an error if you use a forbidden character in code. price$ = 5 # Error print("Price: $5") # OK The character $ is forbidden in names or expressions, but it is allowed inside strings. As of Python 3, the main forbidden characters are: @ $ ? These characters are part of the printable ASCII set. They are legal in strings and comments, but illegal in code structure…  ( 6 min )

When people talk about DevOps, they usually mean something very specific: development teams continuously building and shipping code, and operations teams running and scaling that code in production—usually in the cloud. CI/CD pipelines automatically build, test, and deploy code through staging, QA, and production environments. The boundaries and responsibilities are clear. But what happens when you try to apply this same DevOps concept to embedded software development? Spoiler: it doesn’t fit. At least not in the way most people mean when they say “DevOps.” In embedded systems, developers write software that runs on physical devices. Their workflow looks more like this: They may test features on sample boards, and in some setups, even flash the software to hardware themselves. But that’s w…  ( 4 min )

In Python programming, it's common to define constants that are used throughout your code. These constants, stored in a file like constants.py, can help keep your code organized and make it easier to update settings or values in the future. However, when documenting functions that use these constants, developers often face the dilemma of whether to refer to the constants directly in the documentation or use their values instead. Why Use Constants in Python? Constants like PATH_DATASETS = "data/datasets/" and WIDTH = 416 serve as fixed values that can be reused across multiple functions in your program. This practice enhances code readability, maintainability, and minimizes the risk of introducing errors when changes are needed. The Problem with Documentation When you define a function that…  ( 5 min )

👋 Hello Dev Community — From Guyana with Love! Hey everyone! I'm Nathaniel, a developer and computer science student from Guyana — a small country on the South American mainland. I’m passionate about writing clean code, building full-stack applications, and diving deep into topics like JWTs, web architecture, and system-level programming in C. But beyond that, I’m also deeply interested in how technology is growing (or struggling) in Guyana — from internet access to education to the startup scene. To share dev articles and tutorials, especially things I’ve learned or struggled with as a student and builder. To spotlight Guyana’s tech space, which I think deserves more global attention and internal discussion. To connect with other developers, both in the Caribbean and internationally, and learn from their stories as well. I’ve noticed there's not a lot of content on Dev.to about tech in Guyana, so I want to help change that. Whether you’re here for tutorials, dev opinions, or insights into building a tech career from a small country, I hope my posts can add value. Feel free to reach out, share your thoughts, or even suggest topics you'd like to see discussed.  ( 3 min )

In TypeScript, creating generic functions can significantly increase your code's reusability and type safety. One common requirement is to extract keys from a given type, ensuring that your functions handle different types effectively. In this article, we will focus on how to implement the get_keys() function, which retrieves the keys of a specified type T. Understanding the Requirement The get_keys() function is designed to return the keys of any given type T. This function will be helpful when you want to dynamically work with the properties of objects or interfaces defined in TypeScript, especially when you are dealing with complex data structures. By doing so, you can create a more dynamic and type-safe codebase. Why Use TypeScript's Generics? Generics in TypeScript allow you to …  ( 5 min )

I originally posted this post on my blog. I didn't pay for the most expensive hamburgers I've eaten. An ex-employer did. When I say "most expensive," I mean the same greasy $5 or $10-dollar hamburger from a food truck or a corner in a busy street. But they felt expensive because I ate them while working overnight. In a past job, when my team was lagging behind the self-imposed deadlines of sprints, higher-ups told us: "This sprint is behind schedule. What are you going to do? You're a self-managed team, so decide that by yourselves. But if I were you, I'd choose to work overtime to keep up." "You're a self-managed team" was their subtle way of telling us to work extra hours, without accepting any responsibility. We didn't have any say in what tasks to do and how. We were only a self-managed team when it came to choosing to work overtime. They didn't pay us for that extra time. They only bought us hamburgers. And, when someone raised their concerns about the quality of those hamburgers, they told us we should be grateful because other companies buy their employees nothing to eat. If you're told you're part of a self-managed team, read the fine print. Look for signs of real self-managed teams: Look at job descriptions. Connect with people already working there. Ask follow-up questions during interviews. Otherwise, they might expect you to work overtime without compensation or just buy you an hamburger.

Introducing Secure MCP-gRPC: Enterprise-Grade Security for AI Model Communication By Matthew Stanton | May 12, 2025 TL;DR: Secure MCP-gRPC is an open-source project that adds an enterprise-grade security layer to the Model Context Protocol (MCP), enabling AI models to communicate securely with each other and external tools. It features advanced authentication, comprehensive telemetry, and real-time visualization of model interactions. As organizations increasingly deploy sophisticated AI systems, models need to communicate with each other and with external data sources. The Model Context Protocol (MCP) has emerged as a powerful standard for this communication, but enterprise-grade security and observability features are critical missing pieces for production deployments.

When optimizing Angular applications for performance, developers often overlook a silent culprit: TypeScript enums. While enums improve code readability and type safety, they introduce unexpected overhead in your final JavaScript bundle. This can lead to larger file sizes, slower load times, and diminished performance, especially on mobile or low-bandwidth connections. In this article, we'll explore how enums contribute to bundle bloat, why Angular's build tools struggle to optimize them, and which alternatives you can use to write cleaner, faster, and more efficient code. An enum is a TypeScript feature that lets you define a set of named constants.

🧩 Implementation: @Injectable() export class DestroyService extends Subject { ngOnDestroy() { this.next(); this.complete(); } } 🧩 Question: ngOnDestroy() in this pattern? Even though DestroyService is a service and extends Subject, how does Angular still invoke ngOnDestroy()? 💡 Answer: Even though DestroyService extends Subject (which is not a component or directive), Angular still calls its ngOnDestroy() method if the service is provided at the component level. 🔑 Why ngOnDestroy() Gets Called in a Service ✅ Angular will call ngOnDestroy() if: The class implements OnDestroy AND it is a provider on a component or directive Example: @Component({ Then Angular treats the service like a directive-level provider, and because it has ngOnDestroy(): 🧠 Why It Works Even Though It Extends Subject Subject has no ngOnDestroy(). That's fine. You're extending Subject and adding ngOnDestroy() yourself. Angular doesn’t care that it extends Subject — it just sees: “This class was provided in the component” “It has ngOnDestroy()” ✅ Call it when the component is destroyed 🔁 Summary DestroyService is a service, but it's scoped to the component using providers: [DestroyService] It has a custom ngOnDestroy() method Angular calls ngOnDestroy() on component-scoped providers So you get an automatic, injectable "destroy notifier" for use with takeUntil() This is a neat Angular trick that combines: Lifecycle hooks Dependency injection RxJS into a reusable, composable unsubscribe mechanism.

The CSS Box Model is one of the most important concepts in web design 🧱. It describes how elements are structured on a webpage — every HTML element is treated like a box with layers: content, padding, border, and margin. 💡 What I Made I created a simple webpage using HTML and CSS ✨. It shows a box with the message "Hello Kts". You can view the live demo here: The design is simple but effective — a colored box with space inside and outside, and a border to highlight the shape. 🧠 How the Box Model Works in My Project: Margin: It adds space outside the box (like a buffer from the edges) ➡️ Padding: It adds space inside the box around the text, making it look neat 🧍‍♂️ Border: This creates a clear outline around the box ⚫ Background color: I used a brown background to make the box stand out 🟤 🚀 Why It Matters? Understanding the box model helps you: Control spacing and alignment 🧩 Avoid layout issues or overlapping elements 🚫 Make your design clean and professional ✨ This project helped me understand the basics of styling elements in CSS. It’s a small step, but a strong foundation for building beautiful websites! 🛠️🌟  ( 3 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: That's Entertainment! I built a text adventure game inspired by the history of ancient Pompeii. I believe my text adventure game differentiates itself by adding new features to the UI as you progress through the game. The first feature is a whole new text console that enables you to control and connect the two player characters between time. And the second is a map on the UI enabling you to better understand you position in the game. https://aproulx232.github.io/pompeii-time-out/ https://github.com/aproulx232/pompeii-time-out I used Amazon Q as a visual studio code extension. I have had extensive professional experience with other AI coding tools such as Cursor and Cline. Amazon Q was extremely easy to install and get up and running with the context I already have around AI tools. I found I used the chat feature the most, the same way I would use Cursor chat. The responses and code edits seem to be on par with Cursor. However, multiple times the chat context got stuck and would try over and over to write to my files with no success and no errors to work with.  ( 3 min )

We talk a lot about how smart AI is getting. Not in some sci-fi dystopia. In a real, physical, “it’s-happening-now” kind of way. Every time we ask a model to summarize a doc or spit out a joke, there’s a real-world cost i.e. electricity, water, hardware, minerals. And it adds up. Fast. 🔋 Power Hungry: How Much Juice Does AI Really Need? Let’s start with the basics. Training GPT-3 used up more than 1,200 megawatt-hours of electricity. That could’ve powered over a hundred homes in the U.S. for a full year. Now take GPT-4. That one? Easily 50x more, depending on the estimate. We’re talking small-city-level energy. And guess what? That’s just the training. The real energy drain comes after that, when you and millions of others start using it. Every prompt spins up servers. Add that up over b…  ( 5 min )

In this article, we will explore why Go allows type comparisons that might initially seem surprising, particularly in instances like comparing an integer to a string. We'll explain the underlying mechanisms of Go's type system and how the language handles such comparisons without raising errors or panics. Understanding Go's Type System Go is a statically typed language, which means that the types of all variables are known at compile time. When you define a variable, its type must be explicitly declared or inferred, leading to a robust type safety framework. However, Go introduces a unique feature with the any type, which can hold a value of any type. This flexibility plays a crucial role in our example. The Role of the any Type In your provided code, we see the variable hello is declared …  ( 5 min )

In the competitive world of e-commerce, monitoring prices on platforms like Amazon is crucial for businesses and savvy shoppers alike. However, scraping data directly from such websites can lead to IP bans and access restrictions. To mitigate these risks, using Python in conjunction with proxy IPs offers a safe and effective solution for price monitoring. Why Use Proxies for Amazon Price Monitoring? Anonymity: Proxies mask your real IP address, making it difficult for websites to track your scraping activities. import requests proxy = { http://your_proxy_ip:port", http://your_proxy_ip:port" def get_price(url): # Find the price element (this may vary based on the product page) url = 'https://www.amazon.com/dp/your_product_id' Static and Residential IPs: These are less likely to be flagged by Amazon. Conclusion For more information on reliable proxy services, consider checking out IP2World and explore their offerings tailored for your needs. Happy scraping!  ( 4 min )

When working with Django ORM, you might encounter the need to retrieve distinct records, especially when filtering on a column such as sku.

连续分享了几天的Uniapp跨平台开发鸿蒙应用教程的文章，相信大家对跨平台开发已经有了初步的了解，今天分享一下跨平台开发中的自定义导航栏。 在Hbuilder的初始化项目中是自带了导航栏的，这是一个全局的导航栏，它的样式设置和修改是在全局的配置文件pages.json中进行。 现在打开pages.json文件，在globalStyle中有一些关于导航栏的属性，我们尝试修改一下： { "pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages ], "globalStyle": { 然后看到导航栏已经发生了改变： 这样的修改很方便很便捷，但是好像只有颜色和文字这些基础的属性可以修改，很多时候我们需要在导航栏上添加一些组件，比如按钮或者搜索框。 对于这种情况，uniapp也提供了相应的设置方案，还是在pages.json文件中，当我们需要为某一个页面的导航栏添加组件，就在对应的path路径下设置style，style中有个titleNView属性就是为导航栏添加自定义组件，像这样： "path": "pages/index/index", 但是幽蓝君亲测这种设置方式在浏览器运行时可以正常显示，在鸿蒙中是无效的： 所以在鸿蒙开发中我们需要自己定义导航栏。 再次回到pages.json文件，这次将navigationStyle设置成custom，作用是取消原生的导航栏： "path": "pages/index/index", 然后打开需要自定义导航栏的页面，我这里就直接在首页index.vue中操作，实现逻辑比较简单，就是在页面顶部添加一个导航栏大小的组件，然后在其中添加搜索框，相关代码如下： style="width: calc(100% - 40px);background-color: white;height: 35px;padding: 0px 10px;border-radius: 18px;" .custom-nav-bar { / background-color: #f8f8f8; 导航栏背景色 / 其他样式属性 */ 看一下运行效果： 今天就以添加一个搜索框为例，大家如果需要自定义其他的样式也是类似的实现方式。 以上就是uniapp跨平台开发鸿蒙应用中的自定义导航栏，感谢大家的阅读。  ( 3 min )

Most people think hacking is just about tools, code, or some flashy terminal with green text flying by. But that’s not what makes a real hacker. Let me tell you what really matters—the part only 1% truly understand… Forget the tools for a second. Real hacking starts when you ask the questions nobody else is asking: "Why does this work like that?" "What happens if I try something they didn’t expect?" "What’s behind this system they don’t want me to see?" It’s about curiosity. Obsession. Even rebellion. Not following tutorials step-by-step, but breaking patterns and learning how systems truly work under the surface. I’m teaching myself Python and networking— Not because I want to show off, but because I want to understand how the internet and machines actually think. I’m not here to be just another script kiddie. I’m building a foundation. Quietly. Daily. I don’t want fame. I don’t want likes. I want leverage. I want to be the kind of person who sees through the system—and knows how to bend it. A silent weapon. Sharp, skilled, and always learning. Are you learning just to pass exams? Or are you learning to break limits? Be real with yourself. The world’s already full of followers. We need more builders, breakers, and thinkers. If you feel that fire too—the curiosity, the hunger to really understand—drop a comment. Tell me what you're working on. I’m still early in my journey, but I’m in it for real. Let’s learn. Let’s grow. Let’s hack.  ( 3 min )

RESUMO Palavras-chave: Arquitetura REST. Sistemas distribuídos. API. HTTP. Serviços Web. 1 INTRODUÇÃO 2 DESENVOLVIMENTO De acordo com Stein Junior (2021), REST surgiu da necessidade de criar interfaces simples e eficientes para a comunicação entre sistemas, principalmente via web. O autor afirma que "o objetivo era criar interfaces simples, escaláveis e independentes, facilitando a comunicação entre sistemas distribuídos por meio do protocolo HTTP" (STEIN JUNIOR, 2021, p. 10). A arquitetura REST é baseada na manipulação de recursos — objetos ou entidades de informação — que são identificados por meio de URIs (Uniform Resource Identifiers) e manipulados utilizando métodos HTTP padronizados, como GET, POST, PUT e DELETE. Fielding (2000) ressalta que uma das principais características do REST…  ( 6 min )

Introduction In the world of numerical computing, transitioning from NumPy to JAX can offer significant performance benefits thanks to JAX's Just-In-Time (JIT) compilation and optimizations for GPU acceleration. However, this transition isn't always smooth for all operations, particularly for those that are heavily transformation-based, such as broadcast_to and moveaxis. In this article, we will explore why these functions may perform slower in JAX compared to NumPy and discuss best practices to optimize their usage. Understanding the Performance Discrepancy Why JAX May Be Slower for Basic Operations The performance of JAX can vary significantly depending on the operations being performed. While JAX is designed for efficient numerical computation and can excel in larger batch sizes and com…  ( 5 min )

Let’s not sugarcoat it—workflow automation should be simple. You sketch out a flow, wire up a few APIs, slap in a trigger, and boom: your job runs itself while you sip coffee. Except… not really.
